HAH 4.4.4 An industrial water-distribution system is schematically shown in Figure P4.4.4. The demands on the system are currently at junction D (0.55 m³/s) and E (0.450 m³/s). Water enters the system at junction A from a storage tank (surface elevation of 355.0 m). All pipes are concrete (e = 0.36 mm) with lengths and diameters provided in the table below. In addition, the elevations of the junctions are given in the table. Calculate the flow rate in each pipe (initial estimated flows are provided in Column 2). Solve using the Hardy-Cross method using the the Darcy- Weisbach friction factor. Tabulate each step of the iteration. Also, determine if the pressure at each junction exceeds 185 kPa, a requirement of the water company at the industrial park.
