Question:

In the five-pipe horizontal network of Fig. P6.127, assume that all pipes have a friction factor f = 0.025. For the given inlet and exit flow rate of 2 ft3/s of water at 20°C, determine the flow rate and direction in all pipes. If pA = 120 lbf/in2 gage, determine the pressures at points B, C, and D.
