Free AppAbout NPSHa
Small app to calculate the Net Positive Suction Head (NPSH) available for an installation of centrifugal pump.
Fill up the data:
1. If the suction is connected to a closed tank, fill the internal pressure, otherwise "0" to indicate atmospheric pressure;
2. Local altitude [m];
3. Temperature [°C];
4. Head losses in the suction pipe [m];
5. Suction static head [m];
The app will calculate the available NPSH, absolute pressure at the liquid surface, vapor pressure and liquid density corrected by temperature.
