How to Calculate NPSH of Pump with Examples and
2017-5-21 · NPSH available (ft, m) = absolute pressure (ft, m) – vapor pressure (ft, m) – line loss (ft, m) ± elevation difference (ft, m) NPSHA = 2.31 x 14.7/1 – 2.31 x 0.5/1 – 3 – 10 = 19.8 ft. (for suction lift, elevation difference is minus). EXAMPLE 2: Calculation of NPSH of Pump for Liquid at Boiling Point or Pressured Drum. Figure below ...
