Are there any good libraries for finding air density for Javascript/PHP? I’m not a total chemistry wiz!
Finding the density of air doesn’t require a library, it’s just a single equation.
http://en.wikipedia.org/wiki/Density_of_air
For dry air you use:
density = pressure / (specificgasconstant * temperature)For humid air you use:
density = (drypressure / (specificdrygasconstant * temperature)) + (vaporpressure / (specificvaporgasconstant * temperature))That page has all the various equations you’d need to find the variable inputs (difference between the dry air pressure and the water vapor pressure in humid air) and the constants you’d need as well, and tells how to determine air density by altitude and all that.
