Supercritical CO2 properties versus P & T
Supercritical CO2 properties versus P & T
(OP)
I'm looking for quality data on the density of supercritical CO2 as a function of Temperature and Pressure. Can anyone guide me to a reliable website, or property databook?
Any help appreciated.

Here is the link for completeness:
http://webbook.nist.gov/chemistry/
From the NIST Chemistry Webbook, scroll down and click on
Thermophysical Properties of Fluid Systems
Then select the pure component from the drop-down list.
I believe that these equations are also in the REFPROP software, also from NIST.

Seems almost to good to be true that a java applet can churn out data like this...

The direct, straight path to accurate, recognized, and authoritative Thermophysical Properties of Fluid Systems is:

For quite some years now we’ve been recommending engineers – especially young grads – to use these free and authoritative sources of necessary engineering data. Just some of the past Eng-Tips threads that reflect this are:
thread124-171790: CO2 compression
thread135-170032: Superheated Gas / Flash Liquid Mixing
thread135-145412: Liquid CO2 storage
thread391-161822: R134 properties wanted
thread391-155157: Cryogenic Steam Tables
thread378-150046: N2 amount for pipeline pressure test
thread378-92938: Gas Compressibility factor spreadsheet
This is a great site for:
1) Density;
2) Cp;
3) Enthalpy;
4) Internal energy;
5) Viscosity;
6) Joule-Thomson coefficient;
7) Specific volume;
8) Cv;
9) Entropy;
10) Speed of Sound;
11) Thermal conductivity; and,
12) Surface tension (saturation curve only).
For 34 compounds. It's an excellent site for Thermodynamic data; it’s free, tax-paid, authoritative, accurate, recognized, and you can take it to court as your basis for calculations and engineering decisions. Who would argue against using it as a basis for calculations? It's as authoritative as you are going to get.
