Thermodynamic properties of 1,1,2,2,3-pentafluoropropane.
Author(s) : DEFIBAUGH D. R., GILLIS K. A., MOLDOVER M. R., SCHMIDT J. W., WEBER L. A.
Type of article: Article, IJR article
Summary
The authors report the thermodynamic properties of 1,1,2,2,3-pentafluoropropane (known in the refrigeration industry as HFC-245ca) in the temperature and pressure region commonly encountered in thermal machinery. The properties are based on measurements of the vapour pressure, the density of the compressed liquid, the refractive index of the saturated liquid and vapour, the critical temperature, the speed of sound in the vapour phase, and the capillary rise. From these data they deduce the saturated liquid and vapour densities, the equation of state of the vapour phase, the surface tension, and estimates of the critical pressure and density. The data determine the coefficients for a Carnahan-Starlings-DeSantis equation of state.
