Water is to be moved from one large reservoir to another at a higher elevation as indicated in the figure below. The loss in available energy associated with \( 3.7 \mathrm{ft}^{3} / \mathrm{s} \) being pumped from sections (1) to (2) is \( 61 \mathrm{~V}^{2} / 2 \mathrm{ft}^{2} / \mathrm{s}^{2} \), where \( V \) is the average velocity of water in the 8 -in. insidediameter piping involved. Determine the amount of shaft power required. Assume \( z=86 \mathrm{ft} \).
