air densidy question

[nutz]

does any one know the coralation of temp, hummidty, barometric pressure on the oxogen content of air ?

if so is there a calculation ?

any SAE correction #'s

Its just the Ideal Gas Law but the Density needs to be calced using partial pressures depending on the amount of water vapor in the air and dry bulb and wet bulb temps. Its a tedius calculation by hand. I used to have a spreadsheet I made to do the math for Thermodynamics class, but lost it.

Luckily{for you} I keep this handy SAE Correction calculator bookmarked It also has links to the appropriate equations used in calculating the SAE correction factor.

nice that will help out
