Water flows (v approx. 0) over a dam at the rate of 660 kg/s and falls vertically 86 m before striking the turbine blades. Calculate the rate at which mechanical energy is transferred to the turbine blades, assuming 53% efficiency.

Answer 1

mechanical energy available= mass*g*height

mechanical energy rate= mass/time * g* h

turbine energy= .53*600*9.8*86
