عنوان انگلیسی Thermodynamic Parameters Modeling of Viscous Flow Activation in Ethylene Glycol-Water Fluid Systems
چکیده انگلیسی مقاله Calculation of excess quantities of ethylene glycol + water binary fluid systems at seven absolute temperatures (293.15 to 353.15) K from experimentally determined values of density and shear viscosity were presented in previous work. The examination of related functions beside the quality of correlation from several equations on these experimental values has also been reported. Considering the quasi-equality between Arrhenius activation energy of viscosity Ea and the enthalpy of activation for viscous flow DH*, over with their individual's contribution separately we can define partial molar activation energy Ea1 and Ea2 for ethylene glycol with water respectively. Correlation between Arrhenius parameters also shows desirable Arrhenius temperature. Comparison to the vaporization temperature in the fluid vapor equilibrium and the limiting corresponding partial quantities permit us to predict the value of the boiling points of the pure constituents. New empirical equations to estimate the boiling point are developed.
