My UDS drum lid didn't have the 2" threaded bung hole that many lids have, so I just drilled three closely-spaced 1" holes for my exhaust (I later realized that you actually need FOUR 1" holes to get the same area as a 2" hole, but I was lucky to remember what pi was in the first place...:redface
My question is whether the addition of a short chimney has any real effect on the ability of your exhaust vent to draw off the exhaust. I've heard about "draw" and some seem to discuss a sort of "chimney effect," but is that real? Is there any reason to think that a 2" hole will vent any differently than a 2" hole with a 6" chimney pipe?
I'm no scientist but would appreciate an explanation from someone who is (or at least does a good job of impersonating one), or from those who simply know the answer from personal experience using their cooker.
