Question: A hydraulic turbine is used to generate power by using the water in a dam. The elevation difference between the free surfaces upstream and downstream

A hydraulic turbine is used to generate power by using the water in a dam. The elevation difference between the free surfaces upstream and downstream of the dam is 120 m. The water is supplied to the turbine at a rate of 150 kg/s. If the shaft power output from the turbine is 155 kW, the efficiency of the turbine is
(a) 0.77
(b) 0.80
(c) 0.82
(d) 0.85
(e) 0.88
