Good morning all,

I am about 90% through my reverse smoker build and i have a few questions. It is built out of a 80gal air tank and from the calculations i got from the online calculator, i plan on using a 4" piece of pipe at roughly 31" but trying to stay true to building this 100% with salvaged materials and trying to spend zero dollars on this i am trying to use what i have on hand. For you math gurus on here i want to use a piece of 4" square tube now i know the area of square vs round is different being a square has a smaller surface area, so that being said how much taller does the 4" square tube have to be? Thanks in advance for any help or advice, i would try to load pictures but me and technology don't mix well hahaha
