Hardy Cross Method

Hardy Cross Method

Hardy Cross Method

(OP)
I have created a simple EXCEL tool that uses Hardy cross method to  calculate the water flow  through each pipe in a single loop that consists 6 pipes. The loop is fed by 9 well pumps. I use the solver tool in EXCEL to do the iteration.  Although solver gives me the soltions, still the Delta Q(Assumed flow- Actual flow) in the loop is fairly large. Any thoughts on this?

RE: Hardy Cross Method

sounds like a lot of work. why not try epanet for free?

RE: Hardy Cross Method

You may have reached a point where you have one or more (even all) pipes changing their flow direction and yet the absolute value of dQ remains numerically constant, ie. flows are alternating from +Q to -Q during each iteration.

cvg,

But what about the gain of knowledge and technical  challenge!

Good luck,

Thanks  guys for all your feedback. Yes I can use EPAnet, watergems or infowater. But I am going to develop this tool for  a well field analysis and the loop is the first subcomponent.
