Posted: Sat Nov 12, 2005 2:49 pmHere is one equation for determining air density:
D = 1.325 * Pb/T
D = Denisty of air in pounds per cubic foot.
Pb = Barometric pressure in Hg.
T = Temperature in F + 460
Humidity has a very small influence on density, and is assumed to be 0 (zero). So this equation is called a dry air density equation.
