A proposed, $2\mathrm{.}1-$mile pipeline $(2\mathrm{.}5-$ft$-$diameter; new HDPE pipe$)$ is proposed to carry $73\mathrm{.}04cfs(f\frac{t^3}{sec})$ of water at $4C(39F)$ between two reservoirs. The receiving reservoir is located near Denver, Colorado with $$ 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. Ignore minor losses.
