Estimation of viscosity of liquid hydrocarbon systems

摘要

Based on the principle of intermolecular forces for non-polar compounds, a simple relation is proposed for the estimation of viscosity of liquid hydrocarbons and petroleum mixtures at various temperatures from the knowledge of refractive index. Also some experimental data on the viscosity of some Kuwaiti light and medium petroleum fractions are reported. Evaluation of the proposed method shows that while it is simple it is comparable with other methods available in the literature.
