Overview

Engineering reference data for Air Diffusion Coefficient Gas Mixture Temperature in gases and compressed air.

Key Formulas

Ideal Gas Law

PV=nRTPV = nRT

Pressure × Volume = moles × gas constant × temperature.

Boyle's Law

P1V1=P2V2P_1 V_1 = P_2 V_2

At constant temperature.

Charles's Law

V1T1=V2T2\frac{V_1}{T_1} = \frac{V_2}{T_2}

At constant pressure.

Diffusion Coefficients Data

The diffusion coefficient for a gas mixture in air increases with temperature, as shown in the experimental data below. These values are for binary gas mixtures where air is in large excess, at atmospheric pressure.
