Surface Tension Prediction for Liquid Mixtures
Recently Escobedo and Mansoori (AIChE J. 42(5): 1425, 1996) proposed a new expression, originally derived from statistical mechanics, for the surface tension prediction of pure fluids. In this report, the same theory is extended to the case of mixtures of organic liquids with the following expression, σm = [(1-Tr,m) Tr,m exp (0.30066/Tr,m + 0.86442 Tr,m) (P 0,m ρL,m P 0,m ρv,m)] 4 P0,m = { ΣiΣj...
متن کاملSurface Tension of Nonideal Binary Liquid Mixtures as a Function of Composition.
The composition dependence of the surface tension of highly nonideal organic-organic and aqueous-organic nonelectrolyte solutions is described, based on the assumption that the surface layer can be treated as a separate phase located between vapor and bulk liquid phases. The Wilson, NRTL, and UNIFAC methods are used for activity coefficients of surface and bulk phases and three techniques for c...

متن کاملSurface Tension Prediction of Hydrocarbon Mixtures Using Artificial Neural Network
In this study, artificial neural network was used to predict the surface tension of 20 hydrocarbon mixtures. Experimental data was divided into two parts (70% for training and 30% for testing). Optimal configuration of the network was obtained with minimization of prediction error on testing data. The accuracy of our proposed model was compared with four well-known empirical equations. The arti...
متن کاملThe Liquid Density of Complex Liquid Mixtures
A second virial coefficient correlation suitable for two different temperatures ranges, (T*)-2£180 and (T*)-2>180, where T* is RT/DHvap is presented. The equation of state can be calculated for different, complicated non-polar, and slightly polar liquid mixtures at any temperature over the range from Ttp to T<su...
