A pump draws water at a steady flow rate of 25 lbm/s

through a piping system. The pressure on the suction side

of the pump is 22.5 psig. The pump outlet pressure is 50 psig.

The inlet pipe diameter is 3 in.; the outlet pipe diameter is

2 in. The pump efficiency is 70 percent. Calculate the power

required to drive the pump.
