Web1. Calculation of NPSH available Net Positive Suction Head available NPSHa is defined as the pressure energy that is available to the fluid at the Pump inlet over and above the vapor pressure value of the liquid being pumped at that temperature. The liquid starts with some pressure (generally atmospheric) at the suction reservoir. Web14 sep. 2012 · NPSHA is equal to the absolute pressure head on the liquid surface (Ha) plus the static liquid level above the pump centreline (negative for suction lift) (Hs) minus the absolute liquid vapour pressure head at pumping temperature (Hvap) minus the suction friction head losses (Hf). Ie. NPSHA = Ha + Hs – Hvap – Hf
