Next time you even start to think of any basis for imposing a velocity of 32 ft/s, take a hammer and smash a finger. 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 …...
