Is the tank pressure higher that the regulator pressure? If the tank is

When the tank pressure drops the expansion will also drop. So the
calculation is not trivial.



the cubic feet capacity of the tank refers to quantity of uncompressed
gas at atmospheric pressure. I have a 300 c.f. tank, but it does not
occupy 300 ft of space (equivalent to 10 refrigerators). It only
occupies perhaps 5 cf or so.

Thanks for the correction. After I posted It accured to me that the
capacity as I stated would require
a large tank.

So I stand corrected (informed).
