The difference between the pump discharge pressure and the incoming pressure from the supply source is the net pump discharge pressure when one pumper is supplying another pumper.
PDP = NP +/- H + FL + A Give the formula ample room on the right side so that numbers can be entered and computations can be done. In the formula for the pump discharge pressure, enter 100 psi as NP. The majority of combination nozzles are 100 psi rated. Which of the following is a safe and effective nozzle pressure for? 100 psi (700 kPa) The difference between the pump discharge pressure and the incoming pressure from the supply source is the net pump discharge pressure when one pumper is supplying another pumper.Therefore, the discharge pressure is the sum of the suction pressure and the design pressure of the pump.
