Evaluation and correlation of viscosity data : the most probable values of the viscosity of gaseous propane and propylene

Abstract

The critical evaluation of the viscosity data of gaseous propane and propylene has beed carried out based on the experimental data available in literature. The most probable values of the viscosity of propane are presented in the form of numerical tables covering the range of temperatures from 298.15 to 523.15 K and that of pressures up to 550×10^5 Pa. The estimated uncertainties of the tabulated values are also given. Since there exist only three sets of experimental data available in literature for propylene, the smoothed values are generated on the basis of these data covering the range of temperatures from 300 to 525 K and that of pressures up to 800×10^5 Pa.
