## A Generalized Equation of State for the Thermodynamic Properties of Polar Fluids The 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 p
## Abstract The Helmholtz energy F is written as the sum F = F~H~ + F~A~ + F~Pol~, where F~H~ is the hardβbody contribution, F~A~ the attractive dispersion force contribution, and F~Pol~ either the quadrupolar or dipolar contribution. Here, a new expression for F~A~ is constructed by a simultaneous
## Abstract We propose an equation of state for fluid mixtures of water + ammonia which is expressed in Helmholtz free energy as a function of temperature, molar volume, and mole fraction. IAPWS Formulation 1995 for water and the equation of state by TillnerβRoth and colleagues for ammonia should b
