Water is to be pumped to an atmospheric rooftop storage tank atop a 5-story building, 75 feet above ground-level. A pump station is located at the ground-level. The suction line is a 2-inch ID commercial steel pipe tapped into a municipal supply line maintained at 50 PSIG 5 feet below ground-level. The discharge line is 1.5-inch ID commercial steel, and the total length of pipe is approximately 100 ft. There are two ball valves, a water meter, and gate valve on the discharge line. Determine the pump head required to deliver 40 GPM and the pump power that must be supplied to the water. If a pump is required, what is the motor power required if the pump operates at 55% efficiency?

A Process fluid is pumped from the bottom of one distillation column to another, using a centrifugal pump. The line is a standard commercial steel pipe with a 75 mm internal diameter. From the column to the pump inlet the line is 25 m long and contains six standard elbows and a fully open gate valve From the pump outlet to the second column, the line is 250 m long and contains ten standard elbows, and four gate valves (operated fully open). The fluid level in the first column is 4 m above the pump inlet. The feed point of the second column is 6 m above the pump inlet.
