A pump draws fresh water from a lake to a pool on the hilltop at a rate of 132 kg/min, as shown in the figure. The water enters the pool from a height of z= 110 m (above the water free surface of the lake). The overall efficiency of the motor-pump unit is 75% and the motor consumes electricity at a rate of 3.6 kW. If the irreversible head loss in the piping is 8 m, find (i) the rate of energy loss in the piping (in unit of W), and (ii) the velocity of the water at the pipe outlet at the hilltop. Pump N IK
