It is a holiday weekend and I refuse to embark on such mathmatical formulations.

I don't think that the formula is quite that simple,but then again I haven't started driking yet,LOL!
I'm guessing:
You start with the volume of the tank (approx 5 cubic feet?)
and multiply by 3000 psi (with some factor)to get the total volume of air in the tank. Once knowing that you could figure out how long you could disperse that air at a rate of 50psi at 12CFM.
Can somebody get their school teacher wife on this? (LOL!)
