My favorite reason given to limit the velocities was because it will be too noisy. I told the person, Uh, the building is ON FIRE! WHO CARES HOW NOISY THE WATER MOVING THROUGH THE PIPE WOULD BE!

Hopefully the pain will divert you from wasting your time especially if you're assuming you are dealing with facts. I've heard numerous conclusion as to why the mystical 32 ft/s existed. Only one has any chance of being valid. Joe Hankins told me long ago that FM initially imposed a velocity restriction after hydraulic calc's entered the scene and folks started designing gridded storage systems with 1 inch BLs. For ever other basis, I can hear Andy Rooney saying - Have you ever wondered why ....
