A 20-hp motor drives a centrifugal pump whose efficiency is 70%. The pump discharges water at 60°F with a velocity of 12 ft/s into a 6 in steel line. The inlet is 8 in steel pipe. The pump suction is 5 psi below atmospheric and the friction loss in the system is 10 ft. The suction and dischage lines are at the same elevation. What is the maximum height above the pump inlet that water is available at standard atmospheric pressure?
