Niagara falls is used to provide electricity to 4.8 million homes between canada and the united states. on average, the water falls 96 m to the water turbines, which rotate to provide electricity. approximately 2, 825,000 kg/s of water flows into the combined generating stations. the total electrical power of the stations is 2.525 x 100 kw. determine (a) the average mechanical- to-electrical conversion efficiency of the turbine-generators and (b) the rate of energy loss in the system. assume the inlet and outlet pressure is atmospheric (101.325 kpa) and the water inlet and outlet speed is 10 m/s.
