Maximum PSI Pressure created by DIY CO2
Does anyone know what kind of PSI pressure I could expect to get from using
DIY CO2. I'm not only talking about the initial burst of CO2 usuall ountered, but how much PSI does the fermentation process produce though out it's life. I'm just wondering about estimates (ie: 1-3 PSI, or like 50-70 PSI ?) Thanks, Harry P.S. I know the anwer will depend on how large the container is and how much CO2 is bled off, so let's assume a standard 2 L bottle and a bubble rate of 1 bubble every 2 seconds. Thanks again. -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 80,000 Newsgroups - 16 Different Servers! =----- |

...I'm not only talking about the initial burst of CO2 usuall

This is a tricky question, and the correct answer is that it depends on how deep do you put the outlet of the bottle under water. If the outlet is open to the atmosphere, then the relative pressure of the fermetation process is 0 psi. This is because as soon as the yeast generate the CO2 and let it bubble out of the solution, it escape to the atomsphere, and does nothing to the internal pressure. If the inlet is a few inch below the water, then the pressure will be determine by the depth of discharge (convert inch_H2O to psi). If the outlet opening is constricted (via a needle valve, etc.), then the relative pressure will depends on the size of the opening as well as the rate (volume per hour) of CO2 generation. I can't think of anything that relate the relate pressure (not in a closed container, as you said above regarding the "initial burst".) to the volume of the container. bye -ck- |

Harry,
A few psi, say 1-5 is my experience, not measured. Jonathan "Harry Muscle" wrote in message ... Does anyone know what kind of PSI pressure I could expect to get from using DIY CO2.

Ive seen beer bottles explode, I would think 50 PSI would not be to far
fetched. "Harry Muscle" wrote in message ... Does anyone know what kind of PSI pressure I could expect to get from using DIY CO2.

Maximum PSI Pressure created by DIY CO2
I don't recommend trying to pressurise CO2 from a yeast / fermentation.
I used to make beer and have exploded glass bottles. I don't know what sort of pressure glass bottles are supposed to take, but plastic bottles (like for coke) can normally take around 10 bar (150PSI) before they suffer catastrophic failure. The pressure gives the drink it's fizz. I do not recommend testing this unless you are slightly mad, danger does not scare you and your medical insurance covers injuries due to stupidity. However : take: one bicycle 'track' pump with high pressure capability ( 10 bar) one plastic bottle one old inner tube Remove the valve from the tube and drill the bottle lid to fit. Make sure this is a good seal. Leave a flange around the bottom of the valve so it doesn't push through the hole in the lid. Connect it all together in a way you can easily imagine and start pumping. Wait for the loud explosion and feeling you have been punched in the stomach. Stop pumping, laugh maniacally and do it all again. Half filling the bottle with water can add to the 'fun'. Don't do this with glass bottles. (sorry - totally off topic) Max Jimmy wrote: Ive seen beer bottles explode, I would think 50 PSI would not be to far fetched. "Harry Muscle" wrote in message ...

Maximum PSI Pressure created by DIY CO2
In a sealed container, pressure will go over about 120 psi before the
pressure starts to slow down yeast production. Then it slows down, but I don't know when it stops. However, the question was about an "open" system. I used a check valve as a pressure relief on my DIY system to prevent over pressure. Jonathan "Jimmy" wrote in message m...
