Cooling water for a chemical plant must be pumped from a river 2500 ft from the plant site. Preliminary design cans for a flow of 600 gal/min and 6-in. Steel pipe. Calculate the pressure drop and the annual pumping cost if power cost 3 cents per kilowatt-hour. Would the use of an 8-in. Pipe reduce the power cost enough to offset the increased pipe cost? Use $15/ft of length for the installed cost of 6-in. Pipe and $20/ft for 8-in. Pipe. Annual charges are 20 percent of the installed cost.
