Hydrant Flow Test Calculator | Hose Monster

The Hydrant Flow Test Calculator measures the rated capacity at 20 psi of a fire hydrant. The rated capacity calculation is useful in determining the total water supply at a given point in the hydrant or water main. The calculation offers more useful information than the test flow by itself and is used by insurance underwriters. For more information see NFPA 291, AWWA M-17, or our web page on

Pitot Gauges: How Do I Calculate the PSI to GPM Conversion?

Now that you’ve got a grasp on how PSI, discharge coefficients, and diameter impact a hydrant’s flow rates, try our handy GPM calculator for fire hydrants: Watch this video for another step-by-step example of how to use the pitot gauge’s PSI reading to calculate the rate of water flowing from the hydrant in GPM:

GPM vs. PSI - Firehouse Forums - Firefighting Discussion

30/1/2000· If the fire requires a lessor or larger flow the pump operator is notified as to what we want and the PSI is adjusted to the correct amount equal to the GPM''s we need. Of course you do realize that this only gives us about 90PSI at the nozzle. Summary: It has worked FATASTIC!! I personally have used 1 3/4" hose at low and high pressures and it is not that hard to move around. Try the same

How to calculate the total GPM and pressure in a fire hose

Answer: You have to calculate how many GPM the nozzle is supposed to deliver and at what pressure. Most 1 1/2″ nozzles were 100 GPM at 100 PSI when I was running an engine. Then you have to calculate your friction loss and head pressure and add that to you PDP (Pump Discharge Pressure). Say you

Friction Loss Calculator

The results in a PSI drop (pressure loss) at the other end of the hose. The higher the gpm passing through a hose, the more turbulance and friction loss will result. Friction loss examples: 100 ft 1" @ 100 gpm = 150 PSI 100 ft 1 1/2" @ 100 gpm = 24 PSI 100 ft 1 3/4" @ 150 gpm = 34.88 PSI 200 ft 1 3/4" @ 150 gpm = 69.75 PSI 100 ft 1 3/4" @ 185

How to use: The left column lists the gallons per minute (GPM).The right column is the friction loss (FL), measured in PSI (for each 100'' section fire hose).Start by determining the GPM & PSI being pumped (ex: 1000 GPM & 150 PSI), then scroll through the left hand column

Hose Flow Rate Calculator - Calculator Academy

7/10/2021· Hose Flow Rate Formula. The following formula is used to calculate a hose flow rate. Q = (1946.6 * D ^ 1.857 * (P/L) ) ^ .54. Where Q is the volumetric flow rate in gallons per minute (GPM) D is the internal diameter of the hose. P is the dynamic pressure of water. L is the length of the hose.

HYDRAULICS MANUAL - Local F-33

Fortunately, in the case of fire hose, the friction loss rate (FLR) is a simple function of the square of the amount of water flowing. Specifically, the total gallons per minute (GPM) divided by 100 and then squared and then doubled, has been found to be an adequate fire ground formula for computing the friction loss rate. Once you have determined the friction loss rate for the length of hose

egory: NFPA 14 - MeyerFire

19/7/2021· A more typical firefighting set up in the majority of fire departments would be 1.75” or 2” hose and a 75 psi or 100 psi fog nozzle flowing between 150-200 gpm. I’ll use Bozeman as an example. We use 1.75” hose, a 75 psi fog nozzle, and a target flow of 175 gpm. In our experience the pressure loss per 100-ft of 1.75” hose with 175 gpm is 50 psi. So if we need to stretch 250 ft of

How many GPM '' 5" LDH? - Firehouse Forums - Firefighting

2/6/2016· If you are on a hydrant that can supply the 1,600 gpm at 20 psi residual, you should be able to deliver 1,600 gpm a distance of 1,000 ft. with a PDP of 160 psi. There are limits to this system, because your engine is rated at 150 psi. At 2,000 gpm (pinkie) the loss per 100 ft. is 5 squared or 25 psi. You should be able to deliver 2,000 gpm through 600 ft. of 5" hose. If you try to push these

Friction Loss Calculator - fire department

As water passes through the hose / pipe, friction between the water and the inside surface of the hose / pipe causes turbulence. This turbulence reduces the energy produced by the pump (PSI). As a result, the PSI at the other end of the hose will be lower. The higher the GPM passing through a hose or pipe, the more turbulance and friction loss will result.

United States Department of Agriculture Forest Service

Wye valve 0.46 psi Hose line tee 0.05 psi Hose line tee w/ valve 0.77 psi Based on these results, ignoring friction loss in appliances is more accurate than arbitrarily assigning a 5 psi pressure loss to each appliance in a hose lay. Appliance friction loss should be ignored when determining friction loss in a wildland hose lay. This is true

Universal Friction Loss Formula - Fire Engineering

Therefore, FL for the 700-foot line is 2 psi X 7, or 14 psi, rounded to 15 psi. Note that our “nozzle pressure” will be the desired intake pressure at Engine 1, 20 psi. EP = NP + FL + BP

Pressure Loss Calculator | Pacific Hoseflex

By using calculator below we find that 1400 ft 3 /hour. corresponds to 175 gal/min. Then we plot the 175 gpm on the X-axis of the chart below until we “hit” the line for 2″ hose ID, then by going over horizontally to the Y-axis, we find that Pressure Loss per foot of hose will be about 3.7 psi. So that the total pressure drop over the hose length will be 314.5 psi (3.7 x 85). Download
