)
inlinestatic

Lacking better data on water-air diffusion in liquids, we use at the moment the diffusion coefficient of the air's main component nitrogen!!

Diffusion coefficent $\mathrm{[m^2/s]}$ for molecular nitrogen in liquid water.

The empirical equations for estimating the diffusion coefficient in infinite solution which are presented in Reid, 1987 all show a linear dependency on temperature. We thus simply scale the experimentally obtained diffusion coefficient of Ferrell and Himmelblau by the temperature.
