Great video 👍👍 I was surprised the temp. would drop to -72 C. So I believe frequent use of this cartridge may not be good for the valves and tubes of the bike as I doubt they can handle this low temp. and resulting thermal shock.
Yes you can seriously hurt yourself if you aren’t careful! Holding the cylinder after discharging it really burns if it doesn’t come with a cover. Interesting point about the potential effects of thermal shock on the valve!
Doubt it… the small mass of CO2 inside the cycle would be offset by the power consumption of producing components for higher pressure as well compressing to higher pressures!
@@ChemEngWeekly Plus, the way we extract the various components of air, is to cool them down to extremely low pressures, and sort them by boiling point. This is how we get pure CO2, pure O2, pure N2, and pure forms of all inert gasses other than helium. That process alone would produce more CO2 from the energy required to operate the distillation process, than you'd extract from the atmosphere.
Very good video. Thank You!! What I learned from this video is that the components must be beefed up AND some kind of anti-dri ice mechanism must be installed. The CO2 would be cheap, safe, and not harmful to Ozone but the mechanism to make it work would be expensive. Now I'm wondering how long will a CO2 system last so that it pays for itself like solar panels. I'm also wondering if the CO2 system draws more energy due to having a beefier compressor.
Awesome. The volume doesn’t change, so I’m not sure what you mean. You mean what mass is left when the pressure inside is equal to atmospheric? You can use the ideal gas law to calculate it.

Clever concept idea pat! CO2 in fridges would certainly be interesting, maybe it could have an impact to offset carbon footprints…?

Completely true, did not consider that!

Very interesting video ! I was wondering what is the final volume of the cartridge at 1bar ?
Awesome. The volume doesn’t change, so I’m not sure what you mean. You mean what mass is left when the pressure inside is equal to atmospheric? You can use the ideal gas law to calculate it.
I mean we have a 21ml of compressed CO2 at 58 bar , what would be the volume of gaz once you decompress it ?
Then I'd use (assuming 20 Celsius) PV = nRT = mRT/M, so V = mRT/MP = 16 g × 8.314 J/mol.K × 298 K ÷ 44 g/mol ÷ 101325 Pa = about 9L
