Sea water, p = 1025 kg/m 3 , flows through a pump at 0:21 m 3 /s.

Question:

Sea water, p = 1025 kg/m³, flows through a pump at 0:21 m³/s. The pump inlet is 0.25 m in diameter. At the inlet the pressure is -0.15 m of mercury. The pump outlet, 0.152 m in diameter, is 1.8 m above the inlet. The outlet pressure is 175 kPa. If the inlet and exit temperature are equal, how much power does the pump add to the fluid?
