Calculation of the available net positive suction head in pump suction lines (NPSH)

NPSH module



Program features:

The module calculates the available head of a pump as a function of steam pressure an density of the medium, the geodesic height difference, the system pressure and the geometrical data of the piping.

Each pump has a specific NPSHR. This is the minimum absolute pressure at the suction nozzle at which the pump can operate. To avoid pump cavitation, the NPSHA of the system must be greater than the NPSHR of the pump. In other words, the available NPSH must be higher than the required.

The plant and pump curve may be displayed graphically.
