Design velocities for water mains
Design velocities for water mains
(OP)
I am reviewing engineering standards for my company's irrigation systems. I am looking at design and maximum fluid velocites in our mains and transite lines. They are C-900 or C-905 PVC typically ranging 6"-18". We use reclaimed water. I am concerned that 5 fps may present excessive thrust forces at directional changes (I am looking for conservative specs). Also, I am not sure about a minimum velocity needed to prevent buildup of sediment, etc. Can anybody recommend any good resources on this and related topics.

Sorry about the metric. Funny how you call imperial units British, but we dont use them any more...

It is always a pleasure to read your posts. Nice work.

If the surges are not recurring and are only occasional take a look at the C905 standard and how the working pressure is calculated.
