Problem 4Pipe Flow and Moody'sA farmer is to pump water at 70°F from a river to a water storage tank nearby using a 125-ft-long, 5 in diameter galvanized iron with three (3) flanged 90° smooth elbows and one (1) sharp-edged exit. The water velocity near the river surface is 6 ft/s, and the pipe inlet is placed in theriver normal to the flow direction of water to take advantage of the dynamic pressure. The tankis also open to the atmosphere and the river is open to the atmosphere. The elevationdifference between the river and the free surface of the tank is 12 ft. For a flow rate of 1.5 ft³/sand an overall pump efficiency of 70 percent. Determine the required electric power input to thepump. The density and dynamic viscosity (u) of water at 70°F are p = 62.30 lbm/ft³ and μ =6.556x104 lbm/ft.s. ish (United States)(c)fusing Moody's Diagram mark on the diagram and show how youdetermined your friction factorf=(d)(e)(f)(9) IAccessibility: InvestigateEKL MAKE SURE YOU HAVE THE TABLEShu (include both major and minor losses)hpumpPower (Wpump)1
