An 80-percent-efficient pump with a power input of 36.00 hp is pumping water from a lake to a nearby pool at a rate of 1.5 ft³ /s through a constant-diameter pipe. The free surface of the pool is 80 ft above that of the lake. Determine the mechanical power used to overcome frictional effects in piping. We take the density of water to be Q = 62.4 lbm/ft³. The mechanical power used to overcome frictional effects in piping is 28.8 hp.
