Surface ten sion prediction for binary solutions

The ther modynamic and transport properties of liquids and liquid mixtures have been used to understand the molecular interactions between th e component s of the mixture and also for engineeri ng applications concerni ng heat tran sfer, mass transfer, and fluid flow.O ne of the most strikin g demonst rations of t he intermolecular forces is the te nsion at the surface of a liquid.T he surfacetension (ƴ ), generally e mployed as a quantitati ve index of this tension, is defined as the force exerted in the plane of the surface per unit length (dynes/cm).additionally, surfa ce tension is equal to the change in the Gibbs e nergy in the process of formation of a unit area of the surface layers fr om molecules present i n the bulk of the liquid phase. there are different methods and theori esfor surface tension calculation but in this p aper we d ecided to use lampersk i model that have been applied already, but there is not an y report of this view that is calcula te with these binary solutions.[۱-۴]
