Calculations
Estimation of the required NPSH, using the Thoma factor
Default

Input data

Flow

Manometric height

Pump's rotation

Output data

NPSH

Description

Given the values of flow, manometric head and pump rotation, estimates the required NPSH value. In general, the obtained value is very conservative.
