“…Although we have here illustrated the procedure with only one example for one fluid and one property, the validity of the model for other properties and fluids has been demonstrated in previous work (Román et al, 2005;Mulero et al, 2010b).…”

“…In a previous work (Mulero et al, 2010b), we studied the applicability and accuracy of the model to correlate data from the NIST data bank (NIST, 2005) for four properties (density, vaporization enthalpy, surface tension, and the inverse of the isobaric heat capacity of a saturated liquid) versus temperature for a set of 22 pure substances (mainly noble gases, alkanes, some refrigerants, and water).…”

“…We show here a simple, short Mathematica program that straightforwardly permits obtaining accurate correlations for four thermodynamic properties of a saturated fluid versus temperature, i.e., along the whole coexistence curve (Román et al, 2005;Mulero et al, 2010b). These properties are the liquid density, vaporization enthalpy, surface tension, and isobaric heat capacity.…”

“…We found that this general expression correlates the data (a set of 22 pure substances including noble and common simple gases, some alkanes, water, NF 3 , NH 3 , and R123) with overall deviations smaller than or similar to those of other published models with the same or a greater number of adjustable coefficients. The complete results may be seen in that work (Mulero et al, 2010b). Here, we have described our development of a simple Mathematica program that permits one to make the previous or new calculations for the aforementioned or for new properties.…”

We present a simple program written in Mathematica 8.0 that permits using a general analytical expression to accurately correlate different thermodynamic properties of a saturated pure fluid. In particular, the program permits one to obtain simple analytical expressions for the liquid density, vaporization enthalpy, surface tension, and the inverse of the isobaric heat capacity of a saturated liquid as a function of the temperature along the entire vapor-liquid coexistence curve. The general expression used is the same for all four thermodynamic properties. It takes the values at both critical and triple temperatures as referents and four or fewer adjustable coefficients for each property. The program displays the absolute and relative errors together with wide information about the error distribution. It can be therefore used as a research or a pedagogical tool.
