Manipal MET2011PhysicsWork, Power and Energy
Water is falling on the blades of a turbine at a rate of 100 ~kg / s . If the height of the fall is 100 m , the power transferred to the turbine will be approximately
Options
- A100 kW
- B10 KW
- C1 kW
- D100 W
Correct answer
A. 100 kW
Step-by-step solution
Power = work time = m g h t = ( m t ) g h Given, m t =100 ~kg / s , h=100 ~m , g=10 ~m / s ^2 Power =100 10 100=100 ~kW
