Alarge reservoir supplied water for a community. a portion of the water supply system is shown below. 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 20 °c. from b to c, the system consists of a square-edged entrance, 760m of pipe, three gate valves, four 45 elbows, and two "c elbows. gage pressure at gate valves, and four 90° elbows. all pipe is 508mm 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 80%) and the wall shear stress in section fg. ㅡㅡ z-174 m 152 m pump 91 m-
