QUESTION
Water flows over a dam at the rate of 550 kg/s and falls vertically 80 m before striking the turbine blades. Calculate:
Water flows over a dam at the rate of 550 kg/s and falls vertically 80 m before striking the turbine blades. Calculate: (a) the speed of the water just before striking the turbine blades (neglect air resistance), and (b) the rate at which mechanical energy is transferred to the turbine blades, assuming 60 percent efficiency.
