    Ok, did'nt catch up that your using air. Perhaps you don't need much more for calc the velocity by changing the mol weight?

    Help needed on calculating system pressure during rapid phase transition of CO2

    Thanks again...your right on that, I can follow ideal gas calc's initially. I have some of the information complete to make approp. calc's and I realized earlier that some of the missing info will have to be validated on a test bench sooner or earlier. I have a press available with 1000t...

    Help needed on calculating system pressure during rapid phase transition of CO2

    thank you for your reply. I agree with you that process dynamics are not connected to eq.of state. I didnt understand your "only 3 times bigger than solid liquid fraction", going to look it up now. With temp. in vessel B I meant that the walls of the vessel could be heated by values high...

    Energy Equations Driving Me Crazy

    I found the following info, it might be of help for your calculations: We know that 1.8 grams of CO2 == 61.02in3 so (12/1.8)(61.02)=406.7Vin3 at 1atm We know that 1atm == 14.7 PSI so (406.7) * 14.7 / 150 = 39.86in3 So 12 grams of CO2 will fill 39.86in3 at 150 PSI at 77F. Calculating the...

    Help needed on calculating system pressure during rapid phase transition of CO2

    Dear Members, I am strugling with calculations on rapid phase transition (RPT) of CO2 in a high pressure vessel. I looked everywhere, from isochoric data to ...you name it but can't get there... The question: What will the resultant pressure be when solid or liquid CO2 in area A contacts...
