Air Density Equation

By popular vote a place to add formulas. If you post a formula please make sure your abbreviations are spelled out so it avoids a lot of follow-up postings.  I know a lot of abbreviations are common or taken to be common knowledge. Please be sure to checkout the new FAQ of common abbreviations.

Please post formulas in separate topics, do not add formulas to someone else's post unless it relates to the original post. Also in the topic line make a note of what your posted formula is about . Thanks

Here 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.
