The water system in a suburban area consists of an old 9-inch pipeline 2392 ft. long which conveys water from a pump to a reservoir whose water surface is 332 ft. higher than the pump. Water is pumped at the rate of 2.86 cfs. Determine the horsepower saved by replacing the old pipe with a new 13-inch pipe. Assume the values of f as equal to 0.042 and 0.016, respectively, for the old and new pipes. Neglect losses of head except friction head.
