For All are interested in fluid properties,
and like the shell ;)
fluid.sh is a shell script which utilized wget to acquire fluid properties from the NIST Chemistry WebBook in a format suitable for further processing with shell scripts or e.g. xmgrace. It supports the full functionality provided by the website!
The script takes the same input as command line arguments you need to enter on the web forms. It produces a ASCII text file containing the respective data points in columns headed by a well readable description. The advantage is that you do not need to "click" through three web pages and export the result - you can do it with one command in the shell! This makes it possible to introduce it in shell scripts to automatize the analysis of other data, to compare or just to save time.

PureFluids calculates the Helmholtz free energy for various pure fluids using equations of state (EOS) collected from the scientific literature. Derivatives of the Helmholtz free energy with respect to density and temperature allows the calculation of the following thermodynamic properties:
inner energy U, enthalpy, Helmholtz free energy F, Gibbs free energy, entropy G, heat capacity at constant V cV and P cP, ideal heat capacity at constant P cP ideal , speed of sound w, isobaric expansion coefficient 𝛼, relative pressure coefficient 𝛼P, isothermal compressibility 𝛽, Joule Thompson coefficient 𝜇, isentropic temperature-pressure coefficient 𝛽S, isothermal throttling coefficient 𝛿T, isothermal stress coefficient𝛽P, second virial Bvirial and third coefficient Cvirial, fugacity f and fugacity coefficient 𝜙, compressibility factor z.
