Hi, I have a doubt with Hardy Cross Method.
For one assumed flow at inlet, I've found flow divided into
each tank with satisfying the conditions of Hardy Cross Method through
iterations. Similarly for 2nd, 3rd, etc, assumed flow also I found flow
divided into each tank. But to plot the System curve between total flow
Vs Total pressure at inlet, how to find Total pressure at inlet of
system for a particular assumed flow?
Can I do it like this? With known pressure loss for the corresponding flow in each pipe Total pressure at inlet of system = 1) Pressure loss at pipe 1 + Pressure loss at pipe 2 + Pressure loss at pipe 6 or 2) Pressure loss at pipe 1 + Pressure loss at pipe 3 + Pressure loss at pipe 5 + Pressure loss at pipe 6 or 3) Pressure loss at pipe 1 + Pressure loss at pipe 3 + Pressure loss at pipe 4. or
all three cases will be same sir? Please correct me sir. Though
softwares are there, before using them, I would like to understand how they
work at back end.

Please guide me,
Thank you
