Water is to be moved from one large reservoir to another at a higher elevation as indicated in Fig. P5.116. The loss of available energy associated with \(2.5 \mathrm{ft}^{3} / \mathrm{s}\) being pumped from sections (1) to (2) is loss \(=61 \bar{V}^{2} / 2 \mathrm{ft}^{2} / \mathrm{s}^{2}\), where \(\bar{V}\) is the average velocity of water in the 8-in. inside-diameter piping involved. Determine the amount of shaft power required.
