As part of the design for the absorption unit, it is necessary to estimate the size of the motor necessary to pump the oil to the top of the absorption tower. The oil must be pumped from an open tank with a liquid level 10 ft above the floor and forced through 150 ft of schedule number 40 pipe of 3-in. nominal diameter. There are five elbows in the line, and the top of the tower is 30 ft above the floor level. The operating pressure in the tower is to be 50 psig, and the oil requirement is estimated to be 50 gpm. The viscosity of the oil is 15 centipoises, and its density is 53.5 lb/ft3. If the efficiency of the pumping assembly including the drive is 40 percent, what horsepower motor will be required?Exercise 3 Hydraulic conductivity & stress.
