PhysicsNEET 2021Power and vertical circular motion

Work, Energy and Power

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? ( $g = 10 m/ s^{2}$ )

A.10.2 kW
B.8.1 kW✓
C.12.3 kW
D.7.0 kW

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
