Consider the pipe network below. All flows are in cfs and flow directions are indicated on the sketch. Assume the first Hardy Cross iteration was done in Excel (Loop 1 was done first, then Loop 2, Loop 3, and finally Loop 4), and your job is to assign the flow in each pipe for the second iteration. You hence need to decide where they will flow come from – from which iteration (iteration 1 or iteration 2), from which loop, and if the flowing sign needs to be kept or switched. Assume that each loop is updated automatically as soon as you enter your

decision for all pipes in that loop. Your decisions need to be presented in a table.

Loop 2 AC AD Loop 3 DC CE DE 3 Loop 1 From which iteration? AB BC AC Loop 4 DE EG DF FG B Loop 1 Loop 2 Loop 3 2 Loop 4 E F From which loop? Switch the flow sign? (Yes or No) 1 No 1 No
