The pump of a water distribution system is powered by a 15-kw electric motor whose efficiency is 90 percent. the water flow rate through the pump is 50 l/s. the diameters of the inlet and outlet pipes are the same, and the elevation difference across the pump is negligible. if the pressures at the inlet and outlet of the pump are measured to be 100 kpa and 300 kpa (absolute), respectively, determine the mechanical efficiency of the pump. (page 99).
