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?
Just checking the NIST site...it looks like NIST has expanded the coverage of their database significantly, to about 70+ light gases, hydrocarbons up to C10, and refrigerants. Besides CO2, there is methanol, ammonia and others.
Brilliant site, just awesome, but how rigorous are the calculations? Can it be used in,say, a publication?
Seems almost to good to be true that a java applet can churn out data like this...
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:
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.
