Water falls from a height of 60 m at the rate of 15 kg/s to operate a turbine. It losses 10% of energy due to frictional forces . How much power is generated by the turbine?(g = 10 m/s2)

Power generated by the turbine is,Pgenerated = Pinput × 90100= Mght×90100Putting the given values  Mt = 15 kg/s, g = 10 m/s2, h = 60 mPgenerated = (15×10×60)×90100                    = 8.1 kW
