19. 100% capacity @ 150 psi net pump pressure What are Pump Tests?
70% capacity @ 200 psi net pump pressure
50% capacity @ 250 psi net pump pressure
20. Net Pump Pressure (NEP) is the measurement of the What is Net Engine/Pump
total work performed by the pump: Pressure (NEP)?
a. To lift water into the pump (drafting)
b. To discharge water from the pump
NEP= Suction Side Work(drafting) + Discharge Side
Work
21. Examples: Examples of figuring out
Discharge gauge reads 165 psi but you are getting Net Engine/Pump Pres-
supplied by hydrant @ 65 psi on your intake gauge. sure (NEP)
So the net pressure would only be 100 psi.
Now your are drafting and Intake gauge reads 20"
mercury (-20) and Discharge reads 120 psi. So your net
pump pressure is 140
22. Pump Discharge Pressure (PDP) is: What is Pump Discharge
PDP= Net pump pressure(NEP) - Suction Side Work Pressure?
