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: proportion of pump available power input, pa, which is delivered as pump power output, pu, after satisfying the losses resulting from friction due to the relative motion of internal surfaces and internal leakage; Name: hydraulic efficiency
