Well, if you have "smart water" it knows to reduce speed to the contracted design criteria. Otherwise, it flows from areas of higher pressure to areas of lower pressure following the rules of fluid mechanics.
I had another thought on this velocity thing. Instead of picking the lowest responsible bidder based on price, why not award projects on the responsible bid based on lowest estimated velocity ?

Once the "engineering" is completed, and the pipe sizes and demand area have been determined, with the required safety factor of 10 PSI or 10%, whichever is most inconvenient, what do y'all think happens to the "calculated velocity" in the pipes when the reality pressure acts on the system?
