Lake water is to be transferred to a water-treatment plant by a 7 in. 3500 rpm pump, shown in Fig. 10-11. The flow rate is to be 300 gpm. What is the maximum height that the pump can be located above the lake surface without risk of cavitation? Assume that the water has a mar-

mum temperature of 80 F, the lost head in the suction line is 2 ft of water, and the barometric pressure is 29 in. of mercury
