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.
physics/ math -
mechanical energy available= mass*g*height
mechanical energy rate= mass/time * g* h
turbine energy= .53*600*9.8*86
