Question

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 25s to hit the turbine, then the power delivered to the turbine is approximately equal to
1.15 kw
2.150 kw
3.125 kw
4.15.5 kw

Answer 1

Hi friend,

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!!!!
