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: The output provided by the machine directly to the coupling. Losses in transmission elements outside of the machine, such as gear transmissions and belt drives, are not included; Name: Shaft performance for nominal speed, drive
