Water is pumped from a lower reservoir to a higher reservoir with a pump that draws 20 kW of electrical power. The free surface of the upper reservoir is 45 m higher than that of the lower reservoir. If the flow rate of water is gauged to be 0.03 m^3/s, Decide the power lost to friction in this setup. Take water = 1000 kg/m3
