A hydroelectric power plant operates under a discharge of 500 cfs with 90 % turbine efficiency. The overall head loss is 1.5 times the velocity head in the 7-ft-diameter penstock. With the conditions stated, determine the following: (a.) the power input (hp) to the turbine, and (D.) the power output (hp) expected from the turbine.
