| Summary: | The temperature and pressure dependence of liquid viscosity has been extensively discussed in the chemistry, physics, and engineering literature for over half a century. Thus far, theoretical ab initio calculations of temperature and pressure effects on viscosity have been unsuccessful. Therefore there have been numerous attempts to relate fundamental properties of liquid state models with experimental viscosity, temperature, pressure, and density (η,T, P, ρ) data. This work has resulted in many semi-empirical equations expressing η as functions of temperature, pressure, volume, density, chain length, molecular weight, degrees of freedom, etc. |
