This calculator calculates the npsh available using atmospheric pressure, vapor pressure, gage pressure at the pump suction, density values.

Npsh Available Calculation

kg/m3

Formula:

NPSHa = (Pa-Pv+Pn)/ρ

Where,
NPSHa = NPSH Available
Pa = Atmospheric Pressure
Pv = Vapor Pressure
Pn = Gage Pressure at the Pump Suction
ρ = Density
