Water is falling from a height of 100 m ...

Water is falling from a height of 100 m at the rate of 100 kg/sec. The power delivered to the turbine is approximately equal to 

A

100 kW

B

10 kW

C

1 kW

D

1000 kW

Text Solution

Verified by Experts

The correct Answer is:
A

Given : Height of the water fall (h) = 100 m and quantity of water falling (Q) = 100 kg/s.
Power delivered to the turbine `(P) =Qgh = 100 xx 10 xx 100`
`= 100000 W = 100 kW`
