The impact of high water velocities tends to be self-correcting. When the velocity of water in a pipe is high, the pressure loss in that pipe is also high. If the pressure loss is too high, the pipe size will be increased to reduce the pressure loss, and the velocity will correspondingly go down. I suggest you also read this article. http://www.firesprinkler.org/techservices/articles/watervelocity.html I hope it is helpful.

I use Hydra-Calc and the default is set @ 32, I assume that's feet per second. Where did that number come from, I didn't see anything in the code book.
