Viscosities of a ternary mixture containing CH3COOCH3, CH3OH, and CH3CH2CH2OH atT=298.15 K and atmospheric pressure have been measured over the whole range of mixture compositions. Viscosity deviations and excess molar Gibbs energy of activation of flow for the ternary system were calculated and ...
In an effort to develop and test predictive models for the dynamic viscosity of multicomponent liquid mixtures, some pertinent experimental data are reported in this work. The densities and kinematic viscosities of the quaternary system benzene + cyclohexane + ethanol + n-heptane and its constituent ...
Viscosity of the binary liquid mixture of carbon dioxide and tetradecane Chapter © 2017 1 Introduction The knowledge of thermophysical properties is essential to accurately predict the behavior of pure fluids or mixtures in engineering applications. While theoretical work on viscosities of pure fluid...

Densities and viscosities of binary liquid mixtures of diethyl malonate with isomeric xylenes were reported at (303.15, 308.15, 313.15 and 318.15 K). From the experimental data, deviation in Viscosity (Δη) and excess Gibbs free energy ... GR Satyanarayana 被引量: 0发表: 2018年 Intermolecular...
The dynamic viscosity and characteristic relaxation time at various scale-structural levels of deformation of a shock-loaded medium are determined using concepts of multilevel solid-state mechanics. The notion of the quasi-time fractal dimension is introduced and used to calculate the indicated character...
4.6.4.5Dynamic Viscosity Thedynamic viscosityis the viscosity of a moving fluid; it depends onT,P, and fluid composition. Values for pure H2O, CO2, and, by extension, H2O–CO2mixtures are similar and vary relatively little compared to properties like porosity and permeability; a representative va...
