Does Mary have a valid concern about the pump?
A pump is to deliver 80 gpm of water at 140°F with a discharge pressure of 150 psig. Suction pressure indicates 2 inches of mercury vacuum. The diameter of suction and discharge pipes are 5 inches, respectively. The pump has an efficiency of 70%, while the motor efficiency is 80%. Determine power input to the drive motor.
