3. A centrifugal pump is to be placed above a large, open water tank, as shown in the figure below. Water is pumped at a rate of I
cu ft/s. At this flow rate the required net positive suction head, NPSHR, is 15 ft as specified by the pump manufacturer. The water
temperature is 80°F and atmospheric pressure is 14.7 psi. Assume that the major head loss between the tank and the pump inlet is
due to filter at the pipe inlet having a minor loss coefficient KL.-20. Other losses can be neglected. The pipe on the suction side
of the pump has a diameter of 5 in. The water vapor pressure at 80°F is 0.5069 psia and y-62.22 lb/cu.ft. Determine Z1 for
cavitation not to occur..

diameter is 80 mm and h = 2.5 m as shown in Fig.1. Neglect friction losses. Take the efficiency of
