Now I guess once you know exactly what you want to/or what controls what you do, there may indeed very well be some tables available that might be helpful in determining some effects of sizing blow-off piping and other structures/matters etc. [e.g. per Table No. 17-1 pages 17-5 through 17-8 at http://www.acipco.com/adip/products/Sect17.pdf , and that per this table a flow rate of 1,400,000 MGD (or ~970 gpm) e.g. out from one 6" hydrant lead would result in ~2.54 fps flow velocity in a 12" mainline (if nothing else was also drawing from the main at that time), whereas the flow velocity in the hydrant lead would be ~10 fps during that amount of withdrawal.]
