Area of a circle = pi x r squared
pi = 3.14
r = .5 x diameter
1" circle has radius of .5
area of 1" hole = 3.14 x .5 x .5
= .785
area of 2" = 3.14 x 1 x 1
= 3.14
Based on the posts that people using the 2" bung for exhaust have success maintaining temps and others posting that one exhaust hole causes uneven temps at the grill grid. I decided to go with 7 holes 7/8" around the perimeter which gives me 3.06 sq inches of exhaust. 1" magnets do a good job of covering the holes for shutdown. Temps hold steady for the most part. Lump is a little harder to lock in on temp. I might add one more 7/8" hole in the center. That would give me 3.5 sq in of exhaust.
