All these must be to the right. It's a matter of physics that to accomplish extinguishment, you must put enough water on the fire to overcome the heat being produced. If you dont need to know the exact flow rate, we provide a chart below with some of the most common hose sizes and diameters. Consider the fact that to continue to send firefighters inside a structure to combat fires of ever-increasing intensity, with lines that flow a marginal amount of water, is simply increasing the possibility of firefighter injury and death, without having any appreciable positive outcome on limiting fire damage. If your mind is already made up, click here to browse our selection of 1 1/2 inch, 1 3/4-inch, and 2-inch double-jacket fire hose. The stopping point was 220 psi. There is no single flow volume for fire hose. The high end of the large-flow handline is normally 325 gpm. I've googled and looked everywhere without success for a chart, or listing of flow capacities for fire hose for these sizes 1 3/4", 2 1/2", 3", and 5". All rights reserved. He has extensive hands-on experience using and testing the hoses we discuss at length on this site. This procedure has the decided advantage of having the increased flow rate immediately available on the line working the fire without the time-delay of having to stretch a second line. However, there are a few exceptions. The longer the hose, the lower the flow rate you will have. Since the pressure will not be increased until called for, the officer has time to prepare the crew to handle the increase in nozzle reaction, which is approximately equal to that of a 100-psi nozzle flowing the same amount of water on a 2 1/2-inch line. Some kinks will only lower the flow rate while others may stop it completely. One last term worth knowing is friction loss: a drop in pressure within a hose due to the internal resistance of the water against the hose lining. 2-inch double-jacket fire hose weighs in at 40 pounds dry and flows up to 250 gallons per minute, making it 30 percent heavier (but 100 GPM faster) than the lightest hose. One line, in red, gives the operator the pressure needed to flow 170 gpm on pre-connected attack lines. Suction lines (hose between the reservoir and pump) should not exceed 4 feet per second. To help even the odds, most police departments have converted to heavier automatic weapons. Hoses that flow more gallons per minute tend to weigh more and take more effort to handle. Pressure and Return (any pressure or return hoses) should not exceed 15 feet per second. But well also consider how they perform in commercial and industrial applications. According to that National Fire Protection Association (NFPA), this means the hose can be used at up to 360 psi on the fireground. Fire Hose Nozzle, Inlet Size 1 1/2 in, Bumper Color Black, Grip Type Standard, Activates By Twist, Thread Type NPSH, Body Material Plastic, Flow Rate 80 gpm, For Use With Water, Max. Hose - Water Discharge - Imperial Units Water discharge through 100 feet hoses - at pressures ranging 10 - 200 psi: Download and print Hose Water Discharge Chart 1 psi = 6.9 kPa = 0.069 bar 1 ft (foot) = 0.3048 m 1 gal (US)/min =6.30888x10-5 m3/s = 0.227 m3/h Hose - Water Discharge - Metric Units If more punch is needed, the officer can call for 15 pounds more pressure, which provides an offensive flow rate at 250 gpm. It can be very frustrating to be using a hose and have too little or too much water coming out. We have also relied on him to use and test other hose accessories, like storage reels and spray nozzles. Operating pressures can be determined beforehand and the needed engine pressures marked on individual line pressure gauges with 1/8-inch automotive pin-striping tape available at any auto parts store. He has authored numerous articles for fire trade magazines. 2" 2 1/4" 2 1/2" 3" SMOOTH BORE DISCHARGE DATA POCKET FLOW GUIDE (GPM) 72 74 76 78 80 82 84 86 88 90 92 94 96 98 100 105 110 115 120 125 130 135 140 145 150 175 200 P.O. They are: With these 3 measurements, you can quickly find out your flow rate using an online calculator. The 1 1/2-inch double jacket fire hose provides 5.06 gallons per minute per dry pound of hose (150 GPM / 29.6 lbs dry = 5.06 GPM/pound). Water Flow Time. Leaf Collector & Street Sweeper Vacuum Truck Hose. Until a few years ago, this could have been accomplished only by using complicated and expensive five-part couplings. You can get a rough estimate by assuming that the hose will flow its maximum flowrate with no pressure left at the end of the hose. To read more, visit our article comparing rubber vs vinyl garden hoses. 15 psi - 610 gpm. If 160 gpm is the only flow desired, the 15/16-inch tip can provide acceptable streams up to about 180 gpm, it must be kept in mind that since the main reason for changing to two-inch hose in the first place is to provide flows that parallel those obtained from 2 1/2-inch lines, attempting to flow more water through the 1 5/16-inch tip will not be successful because streams from smooth-bores begin losing their reach and generating high nozzle reaction forces at nozzle pressures over 65 psi. Fire Hose 1-1/2 inch x 100 feet $ 299.00 For Homeowner Swimming Pool Fire Pump 1-1/2 inch x 100 feet Mil Spec 2 ply rubber hose Fire Hose Quick Connectors Note: Fire hose is now in SHORT SUPPLY. This is where the two-inch line comes into play. As firefighters, we need to always look to improve our work environment. No twist to the left is permitted. The fire is not between you and the exit. Flows will sometimes reach 500 gpm, but that is more the exception than the rule. As you can see, the water pressure will have a large affect on flow rate. An example would be watering your garden. Just follow the package directions on how to use the gauge. Trained firefighters use attack hose to extinguish a fire directly or cool the surrounding air. While flow rate will vary based on hose length, hose diameter, and source water pressure, the most common flow rate will be between 10 and 25 gallons per minute. In firefighting, water moved at high pressures can better penetrate burning materials. Knowing flow rate will help you: Both the diameter and length of the hose will affect the flow rate, along with the water pressure of the source (your spigot). To find the friction loss for a 100 foot section of fire hose, find the column with the desired GPM and to its right you'll see the corrosponding friction loss. Firefighters regularly drag, bend, and carry attack hose. So, which hose delivers the most volume per pound of dry weight? Assuming the hydrant stays at 60-psi and you are using 100 ft of open ended 2" hose (pressure drop across the line of 60 psi) you will max out in the area of 300 - 320 GPM. The 1 1/2-inch double jacket fire hose provides 5.06 gallons per minute per dry pound of hose (150 GPM / 29.6 lbs dry = 5.06 GPM/pound). Always check your hose before using and fix any leaks. Two-inch hose has been around for several years. That pressure falloff is just the dynamic pressure of the line, which changes depending on how much of a demand there is on the system. It seems that the real advantage of the 2-inch couplings kicks in at 325 gpm. You can also print this image on a 8.5x11 sheet of paper. It has the same 1 1/2-inch thread size couplings as other attack lines and is as easily deployed by as few personnel. For instance, I know that 200' of 1 3/4" attack line can flow upwards of 200+ gpm (obviously depending on nozzle and pressure) but, I was, I guess, looking for the max capacity of the specified gpm's for the specified hose diameters, or for that matter, the "typical" capacities for those diameters. The SI unit for the flow rate is m 3 /s, but a number of other units for Q . Firefighters cautiously refer to 1 3/4-inch double-jacket fire hose as all-purpose hose. A typical fire nozzle pressure would be up to 100 psi with a diameter of 1 to 1.25 inches. However, this varies widely with hose end designs from 'full-flow' ends which have the same I.D. A. He is a nationally recognized instructor on large-flow water delivery. Paul Shapiro at Fire Rescue Magazine suggests that a single trained firefighter can handle a hose of this sizealbeit with some effort: [D]o we need to be standing up with a 250-gpm flow (or higher) handline taking a beating or is there an easier way? HANDLINE Flow & Nozzle Reaction Chart (1) Number on top in each box indicates flow (LPM), and number on bottom indicates nozzle reaction (KG). Referring to charts 1 and 2, the two-inch hose matched 2-inch hose in every flow category. You can also find hose timers that will shut the hose off for you after a certain amount of time. 85 gpm Flow Rate, Water, NH Item # 6AKC5; Mfr. Many fire departments that feel uncomfortable operating with smooth-bore nozzles are opting for combination nozzles that are designed to operate at pressures as low as 50 psi. In this episode Jeff Shupe reviews the historical evolution of 2" hose and its fit in today's fire service as an intermediate size hose line, balancing high flows with mobility utilizing a. Flow Capacities of Hose Assemblies. Referring to charts 1 and 2, the two-inch hose matched 2-inch hose in every flow category. This had the effect of materially reducing the per-foot cost of two-inch line to little more than 1 3/4-inch hose. There was a 40-psi reduction in the PDP flowing 325 and 400 gpm by using the 2-inch couplings. The flows for the 2-inch started at 265 gpm because it is considered a high-flow handline. View Full Product Details. Proper nozzle selection becomes extremely important if it is desired to exploit the two-inch line's full potential. By following proper procedure for cleaning, use, storage, testing, and inspection, Superiors fire hose can last 10 years or longer. The only part of the equation missing at this point is selection of a nozzle that can provide relatively high flow rates at manageable nozzle reaction forces. Hydrant Flow Test Calculator. We did not get anywhere close to 360 psi on any of the lines we tested. 1. Models can accomodate flows ranging from 25 to 1250 gpm (100 to 5000 l/min) depending on the model. as the hose, down to as much as 1/8" The pressure is sometimes stated as 'head of water'. Thats right, one firefighter can in most cases handle flows up to 350 gpm on a 2 handline with no problem at all, sitting on the hose. A review of the reaction forces of various nozzles that can be effectively paired with two-inch attack lines, shows why. We are assuming your water pressure is 40 pounds per square inch (PSI), which is the most common measurement in homes. SKU: 3775. As we do with all our contributors, we ask him to use his hands-on experience with these hoses to provide authentic advice to our audience. 4. Many firefighters prefer 1 1/2-inch double jacket fire hose as their attack line. The flows for the two-inch start at 185 gpm because this line can be used for both low- and high-flow operations-185, 210, 265, 325, and 400 gpm. This shortage becomes critical during first-arriving-company operations, when relatively few on-scene firefighters have to simultaneously perform command, size-up, rescue and fire suppression operational tasks. During an attack operation, if the officer feels that more flow is needed, he or she will radio the pump operator to increase the pressure to "blue-two." Angus Fire manufactures a range of covered fire hoses including the world's leading BS6391 Kitemarked fire hose Duraline. Q=VtQ=Vt. As water moves through the liner, the friction between the hose and the liner slows the movement of water. The diameter of the hose has a direct correlation to flow rate. Key News and Events SEPT 26-30, 2022 Firehouse Expo Booth 607 Columbus Convention Center Columbus, OH APR 22-24, 2023 of 1/2" hose, at a flow rate of 10 gal./min., is 50 lbs./in.2 (0.5 x 100 = 50 lb./in.2). They are: Hose length (often measured in feet) Hose diameter (often measured in inches) Water pressure from the source (measured in pounds per square inch, or PSI) With these 3 measurements, you can quickly find out your flow rate using an online calculator. Keeping that in mind, we decided to use a short piece of 2-inch five feet long at the end of the two-inch handline for the sole purpose of absorbing nozzle reaction to assist the firefighter with handling the high flows. Superior, a North Carolina-based manufacturer of fire hose, offers each of their fire hoses with their abrasion-resistant Steadfast coating, available in eight colors. Use this when fire flow testing hydrants. delivery of the highest quality fire hose . You will need to know 3 measurements to calculate the flow rate of your hose. Model # 6AKC8 UNSPSC # 46191603 $101.25. If you are wanting a higher flow rate, it is always best to use the shortest hose possible. If it is decided to utilize a 100-psi combination nozzle on the business end, it makes more sense to utilize 2 1/2-inch hose because that line's increased weight can help the nozzle operators to better cope with relatively high nozzle reaction forces. Use these fire hoses and accessories for industrial, residential, or commercial firefighting or other projects requiring heavy duty hoses. But for filling our hypothetical swimming pool, this hose comes in handy. The friction loss for five-inch line flowing 500 gpm is roughly two psi. Once you have the time it takes to fill the container, you can convert this to gallons per minute. The calculation offers more useful information than the test flow by itself and is used by insurance . Sizing Whole-House Water Filter Cartridge Systems. This single unit operates with up to three fire hose sizes: 1.5", 1.75" and 2.5". The most common hose pressure ratings for attack line hose include a 1,200-pound-per-square-inch (psi) burst pressure and a 400-psi annual test pressure. This chart is designed (using the friction loss formula) to find quick and accurate answers for 1 1/2" fire hose friciton loss.To find the friction loss for a 100 foot section of fire hose, find the column with the desired GPM and to its right you'll see the corrosponding friction loss. Foreword; How to Use This Information. Rubber Vacuum & Abrasive Hose. Available . The two-inch hose is manufactured by Key Fire Hose and is the ECO-10 line. Look up the specific flow vs. pressure data for the fire hose. This article focuses on the large-flow preconnected handline with a different twist to it: using two-inch hose for the preconnected high-flow handline to make this big-hit line easier to deploy. The private-dwelling tactical flow rate proposed in NFPA 1710 is based on the National Fire Academy's (NFA) fire-flow formula: NFF = (L X W)/ 3 x % of building involvement NFF = (2000 ft2)/ 3 x .5 = 333.33 GPM Using this equation, the NFPA's private-dwelling tactical flow rate was calculated for a 2,000-square-foot house. (2) Flows may vary with brand or condition of hose. To find the maximum flow you would need to know the maximum pressure. The National Institute of Standards and Technology (the former National Bureau of Standards) has documented the fact that fires are becoming more intense due to increased use of synthetic building and furnishing materials. NOT RECOMMENDED (not recommended) flows in excess of 15 feet per second are not recommened. How does it handle? Assault Nozzles Rated at 100 Psi. Dry Bulk Softwall Discharge Transport Hose. If the water is being lost due to a leak, it will reduce the amount of water getting to the end of the hose. The 2-inch hose did not have a problem with nozzle reaction at all. 10 Best Garden Hose Pots, Boxes & Storage Bins [Decorative]. The friction loss in four-inch hose flowing 500 gpm is approximately five psi. The most common water pressure is 40 PSI. 45M 45M 45M60M 60M 60M75M 75M 75M 3.5 15.5 14 12 10 8.6 7 5.2 38mm HOSE 45mm .

When using two-inch hose in conjunction with 1-inch couplings, its important to remember that the standard for the small handline preconnect plumbing is two inches, which will not be able to support the flows needed for a high-flow handline, at least efficiently. . Call if you have any questions: 702-533-4363 Add to cart SKU: FH100 Category: Fire Pump & Accessories Want to start the conversation? Using this information, we can determine the flow rate (Q) as follows: Q = Area * Velocity Q = (0.349 ft 2) * (16 ft/s) Q = 5.584 ft 3 /s Friction loss increases with the length and flow rate of the hose. When it comes to large-flow handlines, the 2-inch hose has always been the weapon of choice, because its lower friction loss capabilities allow for more flow. If you currently use a specific size of double jacket fire hose and are considering a switch to a different size, youve come to the right place. Garden hoses are pretty simple tools, but understanding flow rate will allow you to use a hose more efficiently. When you connect two hoses together, the flow rate will only decrease due to the added length. Pressure and gallonage provide different benefits to firefighting and pressure washing applications. The end result is that firefighters will pull smaller lines, delivering lower than required flows. Charts 1 and 2 show 2-inch and two-inch lines at 200 feet with corresponding flows and PDPs. AkroFlow Portable Flow Meter Use AkroFlow for precision flow management, so you can know your flow on the fireground. And hoses that carry water at high pressures may feature a double jacket, allowing the hose to withstand higher pressures and abrasion. Firefighters frequently distinguish between attack hose and supply hose. One eastern fire department replaced its 2 1/2-inch pre-connects with a two-inch, 300-foot line that operates with a 1 1/8-inch tip. A fire hoses ability to move large volumes of water makes it an excellent choice for mining companies looking to pump excess water from a quarry bottom. This is usually done by the first-in unit. Because of these negative traits, firefighters will tend to not choose the 2-inch line. Couplings | Double Jacket | FREE SHIPPING | Located in S. CAROLINA. testing, or on the fire ground, whoever receives information can do so away from the water and heat that may cause damage to your device. If the head is given in metres of water, each 1-metre head (3.28 ft) induces 0.1 bar (1.47 psi.) Guidelines issued by the National Fire Protection Association (NFPA) require that the material used withstand damage caused by repeated bending and changes in pressure. This chart is designed (using the friction loss formula) to find quick and accurate answers for 2 1/2" fire hose friciton loss. The 2-inch preconnect has been a great tool for initial attack on a large volume of fire. While available sizes for double jacket attack line hose range from 1 inch to 3 inches, weve chosen to hone in on the three most common diameters: 1 1/2 inch, 1 3/4-inch, and 2-inch fire hose. If anyone could help with providing these figures (in terms of GPM's) or give a link to a source that could help, it would be greatly appreciated. Click here to browse our selection of double-jacket fire hose. While many departments are satisfied with their present handlines and attack strategy when there are enough personnel on the scene to enable the quick deployment of 2 1/2-inch initial or backup lines, a number of progressive fire officers are now investigating the addition of a "day line" one that provides for high flow rates yet can be easily and quickly deployed by the first-arriving firefighters when relatively few people are available, such as during daytime hours. Combatting fires in occupancies of the 1990s requires more water to combat more intense fires. 17-32 of 339 results for "2 inch fire hose" RESULTS 2" x 50ft PVC Lay Flat Discharge Hose With Aluminum Camlock C & E Fittings, Cam Lock Fitting Type A included, Heavy Duty Reinforced Pump Backwash Hose Assembly 53 $5799 FREE delivery Mon, Nov 14 2" x 50' Coupled Aluminum Shank IPT/NPSH Single Jacket Mill Hose (250 LB Test) 5 $10164 Rise: Under the hydrostatic test, no rise . When water has to travel longer distances, the flow rate will always slow down. A unique through the weave construction, guarantees hoses are strong, durable, lightweight, flexible and easy to handle. This will keep you from wasting water or applying not enough water. It is somewhat heavier than 1 3/4-inch hose when filled with water, approximately 65 pounds per 50-foot length vs. 54 pounds for 1 3/4-inch line, but not nearly as heavy as 2 1/2-inch hose, which weighs approximately 120 pounds. Flow of water in Hose Inside Diameter: Often, the same amount of two-inch hose will fit in the hose bed space as the smaller line. The material that your garden hose is made of can greatly affect kinks. Take the square root of 55 psi/57.8 psi, which is 0.9755, and multiply by 850 to get 829.16 gpm. It worked great. Therefore, it is crucial to connect the two-inch line to a to a 2-inch discharge-whether it be a standard 2-inch or one that is designed for a 2-inch preconnect. 1. The question that comes to mind is whether a two-inch attack line will provide the flows that a 2-inch line can produce. 2 inch fire hoses come in single & double jacketed woven polyester, rubber, and even lightweight discharge. It is commonly measured in gallons per minute, or GPM, and assumes a free and open-ended hose (not connected to a sprinkler or a nozzle). The flows for the two-inch start at 185 gpm because this line can be used for both low- and high-flow operations-185, 210, 265, 325, and 400 gpm. . The drawback to using 2-inch line is that it is heavy, making it tough to deploy, especially in a quick-attack mode. Most garden hose diameters are one of three sizes listed below. It is not much larger in flat width than 1 3/4-inch hose. Founded in 1908, Darley is a leading provider of firefighting equipment, rescue gear, tools and supplies. Sensing a need in the market, one coupling company developed an expansion ring drawbar that allowed the installation of inexpensive three-piece couplings on two-inch hose. Because the two-inch will have a higher friction loss at the high flows we tried to achieve, a nozzle with a low nozzle pressure kept the overall discharge pressure as low as possible. You can also use 2-inch line master streams for offensive operations. Knowing the flow rate ahead of time, will help you decide on which hose you may want to buy. Logically, if there has been such a need for greater flow in the 1-inch attack handline, one must also examine the flow rate of the 2-inch attack handline. Rebel Attack Hose Angus Rebel attack hose, is a first responder firefighting hose that can withstand flames . 6-inch rubber covered fire hose designed for the purpose of moving water between a pressurized water source and a pump that is supplying attack lines. Paragraph 18.4.5.3.2 states that the required fire flow for buildings other than one and two family dwellings can be reduced by 75 percent when the building is protected by an approved automatic sprinkler system. Many large cities such as Boston, Miami, Chicago, Los Angeles, Phoenix and Memphis, TN, have switched to low pressure nozzles for offensive attack operations. So too should fire departments investigate and implement better, more effective tactics and methods of combating more intense fires. About 15 feet of pipe at 80 PSI and a 5 foot rise if that makes a difference. If a small hose is easier to use for a firefighter, however, then the job would just be extended, handicapping the crew rather than helping them. Typical flow rate for fire hydrant discharge outlets are as follows 5: 2-inch discharge outlet: 10 psi - 500 gpm. A leak in your garden hose is a common reason of a decreased flow rate. The average rpm range for the two-inch line was 1,700 to about 1,800 rpm. First, its important to understand that the higher pressure used on the hose itself is well within the pressure capabilities for which the two-inch hose is designed. However, the resulting fire flow cannot be less than 1000 gpm (3785 L/min) or 600 gpm (2270 L/min) where quick response sprinklers . With a powerful enough pump, this hose takes 87 minutes to fill a 13,000-gallon swimming pool. Model # 6AKC5 UNSPSC # 46191603 Catalog Page # 1819 1819 For industrial hose, please visit Angus Flexible Pipelines to see the full range. Open nozzle. For years, the only practical hoseline size that could flow over 200 gpm was 2 1/2 inches. Theyre considered easy to deploy and deliver large volumes of water in a short time. This website (heartlandhoses.com) and its content are owned by VFK Digital LLC, a limited liability company located in Kansas, USA. 3. The reason for going to two-inch hose is to make hose deployment easier-especially for one firefighter. The advantages have been for slightly elevated flow and reduced pump discharge pressure (PDP), which reduces engine rpm, reducing wear and tear on the equipment. The stream reaches about 70 feet and, despite the high flow, can be handled quite easily by a trained operator. Fire Hose - 3" x 50' -w-2 Couplings-FREE SHIPPING-Off White. Internal diameter creep in fire hose manufacturing is a problem that is industry-wide. The 2-inch hose delivers an impressive 6.25 GPM per pound of dry weight. However, the output of water increases by 20 percent due to the drop in friction loss and increased diameter. Small and lightweight, this hose maneuvers easily and can even be handled by a single user. The factors that will affect the flow rate of your garden hose are: Lets take a closer look at each one of these and what you need to know for each factor. Dividing 40 psi by five psi equals eight. If you have a 25 foot hose and all have 5/8 inch diameter, the flow rates can be quite different. Pull hose entirely off rack (or else water will not flow). What may have worked in the past may no longer prove effective. The fire is small and does not appear to be spreading. DC Firefighters Rescue Seniors from 8-Story Building, NVFC, VCOS, ISFSI Release Operational Training Guide, LEGO Masters Firefighting Team 'Built' on Friendship. A second line, in blue, indicates the pump pressure needed to flow 240 gpm on the same line. Find it at Grainger.com. The 1 3/4-inch hose delivers 5.29 GPM per pound of dry weightan improvement of less than a quarter of a gallon per pound. Water pressure also has a direct correlation to flow rate. It all depends upon how much pressure you are able to supply in getting the water through the hose line. He has specifically contributed to the testing of hose flow rate, crush-resistance, and weight. https://www.linkedin.com/company/firehouse-magazine. Regarding this, how many GPM can a fire hydrant flow? Actual gallons per minute vary with the nozzle used, available water pressure, and other factors. With the increase in diameter, a 100-foot length of 400 PSI 1 3/4-inch Superior Double Jacket Fire Hose jumps in weight up to 34 pounds dry, making it almost 5 lbs heavier than the same length of 1 1/2-inch hose. The Hydrant Flow Test Calculator measures the rated capacity at 20 psi of a fire hydrant. 1.78" DP17-100S 500 psi 1000 psi 1500 psi 2.125" 0.40 lbs/ft Targeted Flow Rates: 145-175 gpm (1.78") 8 keyhose.com FOR COMMAND AND CONTROL TRU-ID sets new standards for an ergonomic, higher quality, double-jacketed fire hose. As with leaks, you should always check the hose prior to use and remove any kinks. You will need to know 3 measurements to calculate the flow rate of your hose. David P. Fornell goes over the advantages and disadvantages of using two-inch hose. For example, if you have a 5 gallon bucket and it takes 1 minute to fill, you know your flow rate is 5 gallons per minute. Garden hose flow rate is the amount of water that moves from the spigot through the end of the hose over time. Water Hose Flow Rates Air Line Sizing PSI at Hose Nominal Hose Diameters Inlet 1/2 5/8 3/4 1 11/4 11/2 2 21/2 3 4 6 8 . And pressure-washing companies like Denver Pressure Washing Services prefer fire hose when cleaning large or very dirty parking garages. Heartland Hoses is dedicated to providing authentic and data-driven information regarding the performance of garden hoses and other hose accessories. Their respective flows at 50 psi nozzle pressure are 266 gpm and 328 gpm. While there have been hundreds of thousands of discussions throughout the fire service on, for example, the flow merits of one nozzle or the penetration qualities of another, it must be understood that the most important element of attack line operation is gallons per minute (gpm).
