Hi Bin,

The complexity in determining the mutual diffuson coefficient of MEG in hydraulic fuel depends on the fact whether MEG is very diluted - then we can apply the laws of Brownian Motion which is relative simple - or not diluted. If the latter is the case, the mutual diffusivity can de determined by using the free volume theory of diffusion.

Then we would need the mole fractions of the two chemicals and more information on the physical properties, such as critical temperature and pressure, of both chemicals.
