Compressable liquids
 

I am looking for an equation which will allow me to calculate the density of CO2 at 247K (-15 F) and 223 psig (238 psia). I know the density of CO2 at 60 F and ATM to be 9.1621 lbs/gal.

CAN ANYONE OUT THERE HELP ME? I HAVE NO ACCESS TO ENGINEERING MANUALS AT PRESENT.

THANKS FOR YOUR HELP!
