So now I will show you the Formula and how I got the answer above.
Top part of the formula:
1.0 times (1545.348 divided by 28.9644) times (80 plus 459.67) times 1.0
So we moved the 28.9644 to the bottom part of the formula and we get:
1.0 times 1545.348 times 539.67 times 1.0 = 833977.9552
divided by
28.96443 times 144 times 14.6959494 = 61295.01087
or
833977.9552 divided by 61295.01087 = 13.60596798 cubic feet for 1 pound of air mass.
You can do that for any air temp, air pressure, etc to get the cubic feet of air for 1 pound of air.
Same deal you can get the air mass per cubic foot by dividing 1 by the cubic feet above or 0.07349716 pounds per cubic foot
