Physical Property of Liquids and Gases

Many predictions and correlations of thermodynamic physical data have been published [1-3], This chapter reviews physical property data for liquids and gases and presents computer programs to calculate these properties for a range of temperature and correlation constants. Appendix A provides tables of some selected physical property data. 

The programs described cover thermodynamic data of water over a range of temperature from 0°C to 350°C. These data are for density, viscosity, heat capacity, thermal conductivity, surface tension, latent heat of vaporization, and vapor pressure. 

Saturated liquid densities at any temperature are based on the correlation [1]  

The viscosity of a saturated liquid as a function of temperature can be expressed by, 

The viscosities of liquids decrease with temperature. Also, the variation is linear over a wide range of temperatures from the freezing point to the boiling point. This is expressed by the Andrade correlation [7],
