Q. 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/s22)

AIPMT/NEET 2008| W.P.E Q 1 | Falling water will provide energy due to loss in gravitational potential energy but 10 % of it will be lost. Remaining energy will generate power . As power is energy per unit time so when we divide net loss in gravitational potential energy by time , given info about rate will come in use. It’s a good question which is including losses also.
