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/s2g = 10\ \mathrm{m/s^2})

  1. A.10.2 kW
  2. B.8.1 kW✓
  3. C.12.3 kW
  4. D.7.0 kW

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