Piping design problem, vertical piping system for vertical garden wall
(OP)
Hello Everyone,
I am working on a design project that requires to re design the piping system for the vertical living wall. The pump that is utilized is a submersible pump which is connected to a zig zag piping system that has horizontal pipes that are perforated.
Is there a way to calculated the overall head loss through the complete system. See image below as an example

If you can keep the pressure drop across the header from end to end very low compared to pressure loss across the holes then it's relatively straightforward.
Your picture though is much more complex and you will need to iterate and go hole by hole assuming your inlet (no inlet shown on the photo!) with flow and hence pressure drop reducing as you go along. Add in the height difference and it starts getting complex.
As shown you will have more flow out of the bottom holes and less or even none out of the top holes.
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

Try putting the upper holes in the bottom of the upper two rows of pipes, the middle holes (much smaller!) in the middle of the pipe, and only a very few holes in the bottom pipes - but put those in the top of the lower pipes.
