Water is falling on the blades of a turbine from a height of 25 m . 3 × 10 3 kg of water pours on the blade per minute. If the whole of energy is transferred to the turbine, power delivered is:
Options
- A12250   W
- B16250   W
- C8250   W
- D20250   W
Correct answer
A. 12250   W
Step-by-step solution
In physics, power is the amount of energy transferred or converted per unit time. Power, P = m × g × h t ⇒ P = 3 × 10 3 × 10 × 25 60 ⇒ P = 25 × 10 3 2 ⇒ P = 12250   W
