Current Attempt in Progress

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 $4\mathrm{.}9f\frac{t^3}{s}$ being pumped from sections $(1)$ to $(2)$ is $61\frac{V^2}{2}f\frac{t^2}{s^2},$ where $V$ is the average velocity of water in the $8-$in$.$ inside$-$diameter piping involved. Determine the amount of shaft power required.

Assume $z=52ft.$
