Problem Description:
A network of 8 interconnected pipes delivers water from two reservoirs to outlet demands at various pipework junctions.
The network includes 2 pumps, two globe valves and a meter.
The network has two closed loops and one open loop.
Calculate the flow rate in each individual pipe.
Fluid Data: Water at 15° C (assumed).
