Question: Determine the minimum distance a pump should be located below the water surface elevation (Zs) in order to avoid cavitation. The total friction head

Determine the minimum distance a pump should be located below the water surface elevation (Zs) in order to avoid cavitation. The total friction head loss (hLf) is 0.04 meters, and the sum of all minor losses is 0.2 meters. The atmospheric pressure is 101 kPa and the water vapor pressure at 20 C is 2.3388 kPa. The pump required net positive suction head (NPSHR) is 12 meters. 32 2g H-total dynamic head hy+h Gate valve NPSHA Po EGL HGL Palm 1 Datum Absolute zero pressure
