z=174 m A z=152 m H z=104 m B z=91 m Pump G F A pump is used to deliver water from a reservoir to a large tank for a flowrate of 1310 L/s at 20 C. The connecting pipe connects the reservoir at B with a square-edged entrance. From B to C, the pipe is 760 m long and has three gate valves, four 45 elbows, and two 90 elbows. Gage pressure at C is 197 kPa. From F to G, the pipe is 760 m long and contains two gate valves (Kg.v=0.136), four 90 elbows (K90=0.51) and connects the tank with an exit (Kext=1). All pipe is 508 mm in diameter (D) and made by cast iron (e = 0.26 mm). 1) Calculate the average velocity of water in the pipe. 2) Calculate the gage pressure at F. 3) If the pump's efficiency is 80%, calculate the power input to the pump. 4) If the shear stress can be calculated using the equation T = and pg 4 0x hLmajor L Calculate the average wall shear stress in section F-G.
