RE: tentative header size
Use an equivalent internal area technique....
If, for example you have a header to distribute liquid to six seperate taps..... and they are all 4 inch NPS (sch 40....lets say)
Total internal pipe area required is: (6)(12.73 sq. inch) = 76.38 sq. inch
Looking up internal areas for sched 40 pipe, we find that a 10 inch pipe meets the requirements (~78 sq inches)....Therefore, a ten inch header is probably suitable for six 4 inch NPS branches..... Flow velocity should be checked in all branches of a system to ensure that it is "reasonable" (5 to 12 ft/second)
My opinions only......
Anyone else out there !!??

Cheers to you!!! That is the same method I apply when the flow requirement is not known specifically. (and fortunately

Truth: Even the hardest of the problems will have atleast one simple solution. Mine may not be one.
