A dishwasher circulates water at a rate of 55 gpm with a small pump. The total head, P/pg + V^2/2g, leaving the pump is measured to be 120 inches of water. The total head at the pump inlet can be taken as zero. If the power supplied to the pump is 0.4 hp, 1) Determine the efficiency of the pump. The water is sprayed into the dishwasher through four rotating spray nozzles. If the outlet area of each nozzle is 1.5E-3 ft^2 in area, determine: 2) the head loss through nozzles, 3) the efficiency of the spray delivery system (essentially, the nozzles) and 4) the efficiency of the whole system.
