A pump pumps 0.200 cu. ft. per second of brine solution having a specific gravity of 1.15 from an open feed tank having a large cross sectional area. The suction line has an ID of 3.548 in. and the discharge line from the pump a diameter of 2.067 in. The discharge flow goes to an overhead tank and the open end of this line is 75 ft above the liquid level in the feed tank. If friction loses in the pump is 18.0 ft-lbf/lbm, what pressure must the pump develop and what is the pump's horsepower if efficiency is 70%. Assume that flow is turbulent.
