Here's what I've got:
Link to BBQ Pit Calculator
So if I multiply the opening area by 1.5, I get 73 7/8 sq in.
The diameter of the tank is 18 3/4", so the segment height will be 5 7/8" which will give me an area of 73.991.
Am I on the right track with this?
The gap for the reverse flow plate on the other end will also be 5 7/8", no?
