Electric power is to be generated by installing a hydraulic

Electric power is to be generated by installing a hydraulic turbine-generator at a site 115m below the free surface of a large reservoir. If water falling from the surface this height is flowing at a rate of 1350 kg/s determine the power generation potetial.

Solution

power = energy / time

          = m g h / time

          = ( 1350 kg /s ) ( 9.8 m/s² ) (115 m )

          =1.52x10⁶ J/s
