A selected area in Ajloun City is to be served by a water distribution network as shown in Figure 1. A two-loop water-distribution system is depicted in Figurel. The demands on the system are currently at junctions D (550 L/s) and E (450 L/s). Water enters the system at junction A from a storage tank (surface elevation of 355.0 m). All pipes are concrete (CHW of 120) with lengths and diameters provided in the table below. Water flow at 20 °C.
