Question
Please list any assumptions
![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.
