A Reference Equation of State with an Associating Term for the Thermodynamic Properties of Ammonia

Journal of Physical and Chemical Reference Data, 2023
Fluid ammonia is highly associated because of strong intermolecular hydrogen bonding. This causes different behavior of thermophysical properties from nonpolar fluids, as reflected, for example, in the heat capacity. In this work, a new equation of state

Equations of State and Constitutive Equations

Journal of Rheology, 1986
Equations-of state information in the otherwise undeformed state as a starting point for the development of constitutive equations is considered in addition to thermodynamics, free energy functions, and conceptual difficulties including the definition of reference states for strain.

The Equation of State of Helium

Physical Review, 1931
A brief review of the statistical theory of the equation of state is presented. Upon the basis of a recent quantum mechanical calculation of the interatomic energy, the second virial coefficient of helium has been calculated. With the use of the theoretically determined virial coefficient some properties of helium have been computed.

On Equations of State

Proceedings of Latin American & Caribbean Petroleum Engineering Conference, 2007
Summary To predict the phase and volumetric behavior of hydrocarbon mixtures by using an Equation of State; e.g. the Peng and Robinson Equation of State "PREOS", the critical properties in terms of the critical pressure "pc" and critical temperature "Tc" as well as the acentric factor "ω" must be given for each component present in the ...

Universal equation of state

Physical Review B, 1988
The "universal" equation of state recently proposed by Vinet, Ferrante, Rose, and Smith is numerically equivalent, to leading order in finite strain, to several well-established two-parameter equations of state. Notably, it is in accord with the Birch-Murnaghan equation that is derived from Eulerian finite-strain theory, and hence is applicable to ...
