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: Determined total head at the inlet area of the installation, which corresponds to the sum of geodetic head, pressure head and velocity head; Name: Total head at inlet area of the installation
