Q179. How to calculate npsh

Ans.

NPSH (Net Positive Suction Head) can be calculated by subtracting the vapor pressure of the liquid from the total suction head.

  • Calculate the total suction head (TSH) by adding the atmospheric pressure, the pressure head at the surface of the liquid, and the velocity head.

  • Determine the vapor pressure of the liquid at the operating temperature and pressure.

  • Subtract the vapor pressure from the total suction head to get the NPSH value.

  • NPSH = TSH - Vapor Pressure
