I have an application where I need to find the density of a substance at standard conditions (101.325kPA, 15°C) from the density at recorded conditions (varies).
The first application is for natural gas at approximately 11Barg (160 psi, 1100kPA), 80°C (176°F).
The second application is for crude oil at approximately 11Barg (160psi, 1100kPA), 80°C (176°F).
There are standard functions available published by API/AGA to do this but I need a more fundamental thermodynamic description of how to do this.
If somebody can provide a brief explanation I can go away and study in more detail. A description for ideal gases and real gases would be appreciated as well. Obviously in this application the ideal gas theory will be inaccurate.
Thanks
