I have posted about the Density of Air in the past several times.
My old boss had a simple calculation to find the Density of of a Cubic Foot of Air by using a Barometer Reading and a Temperature Reading.
The Formula was Density of Air in Pounds per Cubic Foot
1.326 times for example 29.92 Inches of Mercury
divided by
Temperature in degrees Fehrenheit + 459.6
So 1.326 times 29.92 Hg = 39.35568
85 Degrees F + 459.6 = 544.6
39.35568 divided by 544.6 = .07226 pounds of air mass per each cubic foot of air that is entering the engine.
There are slightly more accurate calculations and calculators out there but this formula is not costing you any money. And you can use it to document your track numbers vs the air entering the engine. Just remember that the Barometer Number must be an uncorrected number.
I will try to post up a couple of simple carb fuel calculations later today.
