A 1 hp electric motor drives a water pump. The pump volumetric flow rate is 2*10^3 m3/s at 300 K.
A) Determine the head loss associated with the pump if the inlet pressure is 90 kPa and the out- let pressure is 300 kPa.
B) Determine the pump efficiency. Neglect kinetic and potential energy difference between the inlet and outlet streams.
