Water falls from a height of 60 m at the rate of 15 kg/s to operate a turbine. The losses due to frictional force are 10% of the input energy. How much power is generated by the turbine ? (g=10 m/s2) (1) 7.0 kW (2) 10.2 kW (3) 8.1 kW (4) 12.3 kW Section -
Option 3) Given, h=60m tm=15kg/s g=10m/s2 Loss due to friction force is 10%, only 90% input is used to generate power, P=ghm/t×90/100 P=10×60×15×0.9 P=8.1kW
