From a reservoir 1,200 m away, a 15-cm-diameter main pipe supplies water to six multistory buildings in an industrial park. The reservoir is 80 m above the datum elevation. The positions of 142 Pipelines and Pipe Networks Chap. 4 the buildings are shown in Figure P4.6.7. The height and the water demand of each building are as follows: Buildings Height (m) ater Demand (L/sec) A 9.4 5.0 B 8.1 6.0 C 3.2 3.5 D 6.0 8.8 E 9.6 8.0 F 4.5 10.0 WII 100 m Gate valve 70 m 80 m 1200 m, 15 cmo 120 m 100 m Main pipe 80 m 80 m 130 m 70 m Figure P4.6.7 If commercial steel pipes are used for the network (downstream from the junction J), what is the correct size of each pipeline? A gate valve (K = 0.15 when fully opened) is installed in the main pipe immediately upstream from the junction J. Determine the material to be used for the main pipe. Determine the water hammer pressure if the valve is suddenly closed. What must the minimum wall thickness of the pipe be to withstand the pressure?
