The answer should be 410 hp and 540 hp. Show how it arrives on that answer in detailed solution.

Transcribed Image Text:The pump-turbine system in the figure
draws water from the upper reservoir in
the daytime to produce power for a city.
At night, it pumps water from lower to
upper reservoirs to restore the situation.
For a design flow rate of 15,000 gal/min in
either direction, the friction head loss is
17 ft. Estimate the power in kW (a)
extracted by the turbine and (b) delivered
by the pump.
