8. Water (p= 1.94 slugs/ft³ and v= 1.1×105ft2/s) is pumped between two reservoirs at a rate of 0.2 ft/s. The piping system consists of400 ft of 2-in-diameter with several fittings as shown in the figure. Minor loss coefficient for12-in bend radius is 0.25. The relative roughness for the pipes is 0.001. Determine the pump horsepower required. (Hint: Watch Video "Chapter 8-Minor losses and pumps.mp4")
