1.	Water falls from a height of 60 m at the rate of 15 kg/s to operate a turbine. The losses due to frictional forces are 10% of energy. How much power is generated by the turbine ? (g = 10 m/s^2)
Answer» 12.3 kW 7.0 kW 8.1 kW 10.2 kW Solution :Mass of water falling/second = 15 kg/s. `H = 60 m, g = 10 m//s^2` , loss = 10% ie., 90% is used Powre generated = `15 XX 10 xx 60 xx 0.9 = 8100 W = 8.1 kW`.
