A pump is to deliver 80 GPM of water at a density of 61.38 lb/ft 3 with a discharge pressure of 150 psig. Suction pressure indicates a 2" Hg vacuum. The diameter of the suction and discharge are 5 in and 4 in, respectively. The pump had an efficiency of 70% while the motor efficiency is 80%. 1. Determine the water horsepower of the pump 2. Determine the brake horsepower of the pump 3. Determine the power input to drive the motor 4. Determine the combined motor-pump efficiency
