The propane burner requires about 10 cuft air for each 1000 btu

water vapor. That's a LOT of water.

How much water is in the water vapor? I'm not doubing the statistics, but
you are saying that 10 cu. ft of air reduces to 16% of vapor by volume.
What else is included here in the 1.6 cubic feet? That means that the
original atmosphere contain 16 percent vapor, but that must be reduced to a
given amount of liquid. How do we calculate the liquid content?
