The difference of elevation between the top of the water of the two reservoirs is 125m. If the top of the water of reservoir B has an elevation of 25m and in between the two reservoirs there is a pump- turbine with a design flow rate in both directions of 120 cubic meter per minute and a head loss due to friction of 15m and an efficiency of 75% for both pump and turbine, Determine the ff: a. the power output by the turbine to draw water from the upper reservoir to produce power to a city and b. the power required by the pump, to pump water from the lower reservoir to the upper reservoir to restore energy to the upper reservoir.
