Description: Pressure at the pump inlet port, including the pump acceleration pressure in the inlet, minus the vapor pressure, at the given fluid temperature; Name: Net positive entry pressure
Description: total pressure (including velocity pressure) at the pump inlet connection less the liquid vapour pressure at the present temperature of the liquid; Name: net positive inlet pressure
Description: greatest difference between the total energy height at the outlet side of the pump aggregate and the total energy height of the intake side of the pump aggregate at operating point; Name: maximum feed height
