Pressure Dependence of The Diffusion Coefficient
For self-diffusion in gases at two different pressures (but the same temperature), the following empirical equation has been suggested:
where:
- P1 and P2 denote pressures 1 and 2, respectively
- D is the diffusion coefficient (m2/s)
- ρ is the gas mass density (kg/m3)
