A proposed, 2.41-mile pipeline (2.5-ft-diameter; new HDPE pipe) is proposed to carry 77.87cfs(ft3/sec) of water at 4C(39F) between two reservoirs. The receiving reservoir is located near Denver, Colorado with a water surface elevation of 5,280ft. MSL. The supply reservoir is being constructed in the foothills near the city. Determine the required water surface elevation of the supply reservoir using the Hazen-Williams equation? Ignore minor losses. (CHW=150)
