During a laboratory test on a water pump appreciable cavitation began when the pressure plus velocity head at inlet was reduced to 3.26 m while the total head change across the pump was 36.5 m and the discharge was 48 L ·s−1. Barometric pressure was 750 mm Hg and the vapour pressure of water 1.8 kPa. What is the net positive suction head in m? If the pump is to give the same total head and discharge in a location where the normal atmospheric pressure is 622 mm Hg and the vapour pressure of water 830 Pa, by how much must the height of the pump above the supply level be reduced?
