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 5.8ft3/ seing pumped from sections (1) to (2) is 61V2/2ft2/s2, 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=45ft
