From a dam, water is pouring down at the rate of 150 kg/s, on the blades of a turbine. If a ball dropped from the same dam takes 2 5s to hit the turbine, then the power delivered to the turbine is approximately equal to (Take g = 10 m/s2)

Hi friend,
First we find the height:
√ h = gt2/2
= 10 · (2 5)2/2
= 100 m .
Now we can find power:
N = ∆mgh = 150 · 10 · 100
= 1.5 · 10^5 W.
(Or)
= 150 kW .
Hope this helped you a little!!!!
