A residential area located in an urban zone of Basrah governorate is served by the triangular pipes loop shown in the figure below. The total population of the area is 10000. The water is assumed to be drawn from four nodes. Estimate the outflow from each node and the required inflow to the network. All the network pipes are DI and placed at a level of -1.5m. The water pressure in the network must not be less than 196.2 kPa. The network is fed using a pumping station composed of three pumps (2W+1S) connected at parallel. The characteristics of each used pump are given below. The feed pipe (from the pumping station to the network) is DI and has a total length of 200m and a diameter of 300mm.
