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: pump h(q) curve where the maximum head (peak point) and shut-off head are not coincidental, or the total head does not decline continuously as the rate of flow increases; Name: stable pump H(Q) curve
