The group contribution method 'UNIFAC-VISCO' has become popular because of its reliable predictions of dynamic & kinematic viscosities, but suffering from a serious drawback for non-availability of sufficient group interaction parameters. A new approximate technique has been proposed in this study, in which the so called UNIFAC-VLE parameters can be used instead of the original UNIFAC-VISCO parameters. This technique was tested for 28 binary liquid systems of different categories & the values of overall AAD (%) for 7 classes of organic binary liquid systems were found to be below 6.1%. These...
