oups.com... Well, if I figured this right: P = n * R * T / V Whe P = pressure in atm n = amount of substance in moles R = Thermal expansion ( 1atm / K*mol ) T = Temp change in Kelvins V = Volume of a sealed container in Liters ( n ) for CO2 is 22.727mol ( R ) for CO2 is 0.08206 ( T ) is 298K ( V ) is 6.81322 Liters Ignoring the air present in the container when it was sealed, and introducing 1 Kg (2.2lbs) of dry ice in my 6.813 L tank, while the air in my living room is 24 C (75 F) final pressure inside the tank will be 8238.7 psi. Oh, crap. I get about 1200 psi. Your formula gives you about 81 atm. 1 atm = 14.7 psi. You should be fine if you go with 1" thick steel. dwhite |

Hey, you know what? You are right..... I went back and checked my
little engineer's book........ 1atm=14.7psi.......not 101.3psi Thank you. If nothing else it makes me feel better about my tank |
