Water falls from a height of 60 ~m at the rate of 15 ~kg / s to operate a turbine. The losses due to frictional forces are 10 % of energy. How much power is generated by the turbine? (g=10 ~m / s ^2 )

Step-by-step solution

Power generated by the turbine is, aligned P_ gene rated & =P_ input 90 100 & = M g h t 90 100 aligned Putting the given values aligned & M t =15 ~kg / s , g=10 ~m / s ^2, h=60 ~m & P_ generated =(15 10 60) 90 100 &=8.1 ~kW aligned
