How to determine aerator CFM
(OP)
I have a need to create an aeration tube in the bottom of a large storage tank. I plan on using 2" PVC pipe with a series of holes. I will construct a hexagonal shape with the PVC and place it in the bottom of the tank. I want to use an air compressor with a plate rating of 140CFM to aerate the liquid, at about 7PSI. My question is, is there any calculation I can use to determine:
1. Number and size of holes
2. Ensure the pressure is sufficient around the entire hexagon
3. Determine if 2" is the correct PVC pipe size to use?
Thanks,

Look for the air flow tables at www.engineeringtoolbox.com
That will get you close enough for pipe sizing, because actually your air will not be arriving at the end of the pipe. Its all gone by then, which is why I think its better to keep the lengths short by feeding from multiple points. In fact I would think it would be better to forget a ring and feed 4 "T" assemablies from the center of the tank (the bottom of that "T"). If you feed the ring from one end, it will be hard to get uniform air distribution around such a long ring.
