Surface Tension Prediction for Liq uid Organic Solvents

Surface tension (ST ) is an impo rtant property in the study of physics and chemistry at fr ee surfaces. Such data a re of importance to scientists, engin eers, and practitioners in many fiel ds such as c hemical pr ocess and reactor engin eering, flow and transpo rt through porous media, materials selection and engineering, biomedical and biochemical en gineering, electronic an d electrical engineerin g, etc.[۱]. When exp erimentally measured ST data ar e not readily available, theoretical or empirica l methods may be used to establish acceptable ST values f or prelimin ary screen ing purposes.Theoreti cal method s of calc ulating ST based o n thermod ynamics can be comple x and require additional chemical properties and simplifyin g assumptions to com plete the calculations. I n this paper, we use so me models for predictin g surface tension of organic solven ts and then compare the results.
