Vertical flow retarder
Vertical flow retarder
(OP)
Hello All. We have a vertical discharge waste water pipe 24 inch dia and 200 feet drop (Ten lengths of 20 feet each.) To slow down the flow each length is packed with bundles of 4 inch dia plastic pipes,each bundle is built from 14 pipes 3 feet long. Each bundle is out of line with the next one so the flow down one 4 inch pipe then splits on entering the next pipe etc etc The 24 inch dia by 20 feet lengths have a spacer flange between them which is only 18 inches inside dia (like an orifice plate).
My question is :- I think I partly understand the idea behind this arrangement but does it have a name - - what is it called and where can I read up on the theory of it.
Thanks in advance.

An (existing) 200 foot drop with an (existing) 24 inch diameter penstock even operating part-time is a lot of money. (Er, free energy).
