A large reservoir supplies water for a community. A portion of the water supply system is shown. Water is pumped from the reservoir to a large storage tank before being sent on to the water treatment facility. The system is designed to provide 1310 L/s of water at 20oC. From B to C the system consists of a square-edged entrance, 760 m of pipe, three gate valves, four 45o elbows, and two 90o elbows. Gage pressure at C is 197 kPa. The system between F and G contains 776 m of pipe, two gate valves, and four 90o elbows. All pipe is 508 mm diameter, cast iron. Calculate the average velocity of water in the pipe, the gage pressure at section F, the power input to the pump (its efficiency is 74 percent), and the wall shear stress in section FG.
