A dam is situated at a height of `550m` above sea level and supplies water to a power house which is at a height of `50 m` above sea level. `2000 kg` of water passes through the turbines per second. What would be the maximum electrical power output (in `MW`) os the power house if the whole system were `60%` efficent ?

Text Solution

Verified by Experts

The correct Answer is:
6
A dam …………
`P = eta (mgh)/(t)= eta m gh`
`= 0.6xx2000xx10xx500=3xx10^(6)W=3MW`
