Abstract
AbstractThe generalized relationships of Lee and Kesler for the thermodynamic properties of nonpolar fluids have been combined with an accurate equation of state for water which is utilized as the reference substance for polar fluids for reduced temperatures from 0.4 to 2.5 and reduced pressures to 10. The input data required are the critical temperature, critical pressure, acentric factor, and a polarity factor Y obtained from experimental pressure‐volume‐temperature data. Comparisons between calculated and experimental thermodynamic properties indicate that highly accurate results are obtained by the method of this study for most polar fluids. A modified procedure is presented for the compressibility factors of substances with large acentric factors such as alcohols. Tabulated values of the polar fluid correction terms are presented for the compressibility factor, fugacity coefficient, and enthalpy, entropy, and heat capacity departures for the complete range investigated.
