Answer to Question #150983 in Chemical Engineering for neo

Question

A centrifugal pump is to be placed above a large, open water tank, as shown in the figure below,
and is to pump water at a rate of 0.0142 m3
/s.
At this flowrate the required net positive suction head, NPSHR, is 4.572 m, as specified by the
pump manufacturer. The water temperature is 30 ºC and atmospheric pressure is 101.325 kPa.
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 of 3.1 m. The pipe on the suction side of the pump has a diameter of
0.1016 m. Determine the maximum height, z1, that the pump can be located above the water
surface without cavitation
