2019/8/30· Static Pressure: 70 psi Residual Pressure: 65 psi flow at 20psi= 3,039 gpm * Most remote sprinkler demand 225gpm @min. residual pressure at system inflow node= 72psi * Hose allowance for Ordinary 1 = 250gpm, @ 65psi per NFPA 7.8.1 for 1-1/2" hose

Enter your appliion’s fluid properties, hose and coupling specifiions, and our Fluid Flow Pressure Calculator will help identify your operational issues, so you can eliminate costly downtime, improve efficiency, and save money.

hose used by the Bonita-Sunnyside Fire Protection District. Calculate the approximate amount of available water flow at a specific hydrant. Describe the specific information needed to set up a relay pumping operation.

Use this calculator to determine the flow rate of any nozzle at any operating pressure. Inputs to this calculator are the nozzle type, current operating pressure and flow, desired flow or desired pressure. Not sure? Specific gravity is the ratio of the density of a fluid

Our Flow Rate Calculator will calculate the average flow rate of fluids based on the bore diameter, pressure and length of the hose. The effects on the predicted water flow are then given in three graphs where in turn two of the variables are kept constant.

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:

2000/6/2· For instance, a gauge reading 100 psi pumping an 1 3/4 and a gauge reading 100 psi pumping a 5" line will have vastly different flows! You''ll need to get ahold of a friction loss chart and a pitot gauge or some manufacturers info on your nozzles.

Calculate required total flow rate, pipe length & friction loss for a sprinkler lateral based on the nuer of sprinklers per line, spacing, pipe size and type. The Equation This calculator uses this formula to determine the Total Flow Rate, Total Pipe Length, and Friction

Use our Fire Pump Test Hose Caclulator to estimate how many hoses will be required to test a particular pump. Simply enter the fire pump and test information below. The results are based on the maximum flow required and friction loss to the flow device. There is

Each fire department must determine what it considers to be a manageable hoseline; some may consider it a hoseline with a pump pressure of 160 psi or less while another may be comfortable with 185

Use this calculator to determine the flow rate of any nozzle at any operating pressure. Inputs to this calculator are the nozzle type, current operating pressure and flow, desired flow or desired pressure. Not sure? Specific gravity is the ratio of the density of a fluid

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 yo
