100% capacity @ 150 psi net pump pressure
70% capacity @ 200 psi net pump pressure
50% capacity @ 250 psi net pump pressure - Answer What are Pump Tests?
Net Pump Pressure (NEP) is the measurement of the total work performed by the pump:
a. To lift water into the pump (drafting)
b. To discharge water from the pump
NEP= Suction Side Work(drafting) + Discharge Side Work - Answer What is Net Engine/Pump Pressure
(NEP)?
