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 the buildings are shown in the Figure below. The height and the water demand of each building are as follows Buildings Height (m) 9.4 7.0 8.1 6.0 3.2 3.0 6.0 7.8 9.6 8.5 4.5 10.0 Water demand (L/sec) If commercial steel pipes are used for the network (downstream from the junction J), A gate valve (K = 0.15 when fully opened) is installed in the main pipe immediately upstream from the junctionJ Using appropriate software a) Determine the correct size of each pipeline b) If no reservoir was to be used and instead a pump will be used. What are the characteristics of the best pump to be used? c) f the water demand varies with time at each building according to the Table below how would your design be different?
