A double-loop pipe network is shown in Figure P8.48. The lengths of all pipes are 700 ft and the C value for each pipe is 110. The elevations of the nodes are as follows: A (200 ft); B (150 ft); C (300 ft), D (150 ft), E (200 ft), and F (150 ft). If the pressure at node C is 40 psi, what is the flow rate and direction of flow in each line, and what is the pressure at each node?
