Problem $5\mathrm{.}116($Suggest starting by using equation $5\mathrm{.}82$ and determining $w_5.$ You can make the starting point water at the surface of the lower reservoir and the ending point water at the surface of the upper reservoir. "Loss of available energy $"$ is equivalent to frictional loss, i$.$e$.{?}_1$ loss ${?}_2.$ Get $w_s=3174\mathrm{.}5ft-l\frac{b}{s}$lug. Answer is $28$ hp $).$
