An effluent holding pond to be used as part of a spray irrigations system is being built. The holding pond is located 2.5 miles awary for the 10 mgd WWTP which will supply the effluent. The effluent will leave the plant at an elevation of 65 feet with 8 feet of driving head. The elevation of the discharge pipe is 55 ft. Determine the pipe diamenter reuired to transport the effluent to the holding pond. Use galvanized iron as the pipe material (e = 0.006 in). Solve the problem using the Darcy Weisbach equation and the Colebrook-White equation. Size the pipe to the nearest inch. Assume the water temp is 80 degrees F.
