Water falls from a height of 60m at the rate of 15 kg/s to operate a turbine. The losses due to frictional force are 10% of the input energy. How much power is generated by the turbine?

8.1kW

12.3kW

7.0kW

10.2kW

Text Solution

Verified by Experts

The correct Answer is:

`P_("in")= (mgh)/(t) =(15 xx10 xx60)/(1) = 9000 W`
`P_("out") = 90%` of `P_("in") implies8.1 kW`
