How can we find the different fluid properties from the various equations of state (EOS) Such as the Virial Equation and Peng Robinson equation of state?
It's the same for any chemically-stable fluid (that doesn't chemically change over the range of pressures and temperatures). Get the constant-pressure specific heat of the zero-density gas from the NASA Glenn report. This is the ideal part. Then derive an expression for the residual enthalpy (the nonideal part) and add the two. I attached the formulas for residual enthalpy. You can easily program the entire thing in an Excel macro. There's more information in this book, which will be free tomorrow (3/14): https://read.amazon.com/kp/embed?asin=B07Q5L1CHT&preview=newtab&linkCode=kpe&ref_=cm_sw_r_kb_dp_9B0F20GYBXBZD4FWNDN2
I have attached the file for methanol that comes with AllProps. The software is VB6 and will not run on recent versions of Windows but you can get it online if you have some way of running it (an old machine or a virtual box). You can find the reference online (listed in the file), which contains the various formulas using the coefficients. The second file is from NIST's REFPROP, which you can get free online and is a very good reference and tool. So what do you hope to do with this? Are you studying thermodynamics?
For anyone else looking for the properties of methanol, here is a spreadsheet with all the thermodynamic properties based on NIST's REFPROP. A simple Excel macro is all you need to create these tables and graphs for any substance in their database (see NIST documentation for details).
