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 130 m. The water is supplied to the turbine at a rate of 150 kg/s. If the shaft power output from the turbine is 140 kW, determine the efficiency of the turbine.
