In the above example problem, a hydroelectric turbine at the base of a dam is shown schematically. The height of the water above the turbine station given as 115 m. This turbine produces 4.6 MW of electricity, and you may assume the losses in the system to be equivalent to 10 m of head of water. The diameter of the pipe at the turbine exit is 0.75 m , and the velocity of water exiting from the pipe is 12.5 m/s. Calculate the efficiency of the turbine.
