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)

Famous quotes containing the words pressure and/or dependence:
“The universal social pressure upon women to be all alike, and do all the same things, and to be content with identical restrictions, has resulted not only in terrible suffering in the lives of exceptional women, but also in the loss of unmeasured feminine values in special gifts. The Drama of the Woman of Genius has too often been a tragedy of misshapen and perverted power.”
—Anna Garlin Spencer (1851–1931)
“As, therefore, we can have no dependence upon morality without religion;Mso, on the other hand, there is nothing better to be expected from religion without morality;Mnevertheless, ‘tis no prodigy to see a man whose real moral character stands very low, who yet entertains the highest notion of himself, in the light of a religious man.”
—Laurence Sterne (1713–1768)
