[b]HOW DO I DESIGN A TANK INLET DIFFUSER[/b] - API

Aug 05,2006 cylindrical tanks inlet diffusers#0183;About all you could do is figure a pipe the same diameter of the inlet line extending 1/3 of the way into the tank with a bunch of 2 holes along it's length.Include an end plate and supports.Don't weld the supports to both the tank bottom and the diffuser but do restrain it from lifting off the supports.What product? What inlet velocity? How high above bottom? Going the Big Inch! http://virtualpipeline.spaces.msnIf I remember right,API-650 gives a recommended maximum velocity for fluid going into the tank to prevent static build-up,so that's one consideraBasically,you want the exit velocity from the diffuser to be no more than 3 feet per second or 1 meter per second. In the simplest form,you just1Thanks for the input,YOU'VE REALLY HELPED A LOT! We are in the estimating stage of this tank.The client said they will be providing specifics sucYou can't possibly do a real estimate without the fill rate. About all you could do is figure a pipe the same diameter of the inlet line extendingThanks again.I'll keep your advice in mind.Question At what point or circumstances might I want to have the inlet line branch off into multiple outlets in the tank? The reason I ask is thatSounds like on of mine! Possibly for mixing,maybe for distributing liquid or gas throughout the tank,maybe because the inlet rate was so high thJust might be to get a nice even level lift on the roof.
