Simple Functions for Predicting Thermodynamic Properties of Ammonia-Water Mixture (RESEARCH NOTE)

The engineering calculation and simulation of absorption refrigeration systems require the availability of simple and efficient functions for the determination of thermodynamic property values of the operating fluid. This work presents a set of five simple and explicit functions for the determination of the vapor - liquid equilibrium properties of the ammonia-water mixture. The functions are co...

Thermodynamic Properties of Metal Amides Determined by Ammonia Pressure-Composition Isotherms

Thermodynamic properties of Mg(NH2)2 and LiNH2 were investigated by measurements of NH3 pressure-composition isotherms (PCI). Van’t Hoff plot of plateau pressures of PCI for decomposition of Mg(NH2)2 indicated the standard enthalpy and entropy change of the reactions were ΔH = (120 ± 11) kJ⋅mol (per unit amount of NH3) and ΔS = (182 ± 19) J⋅mol⋅K for the reaction: Mg(NH2)2 → MgNH + NH3, and ΔH ...

Thermodynamic Properties for Argon

An analytical equation of state is applied to calculate the thermodynamic properties for argon. Theequation of state is that of Song and Mason. It is based on a statistical-mechanical perturbation theory ofhard convex bodies and can be written as fifth-order polynomial in the density. There exist three temperaturedependentparameters: the second virial coefficient, an effective molecular volume,...
