My question concerns co2. I'm toying with the idea of making a co2 generator, using fermentation. My question is about pressure. Say you take a 2 gallon vessel, with a pressure gauge, fill it with the right ratio of sugar, water, and yeast, completely seal the vessel , how much pressure will the SWY mix generate?

If the tank was completely sealed..........It would blow up.

why? Want to refill your paintball can with this system?
I don't understand why you are looking for pressure.
Yes, cO2 is heavier then air, but won't drop like a rock. Co2 was the first widely used shielding gas for welding back i the 20s They switched over the argon with a bit of CO2 in it because the Co2 was too light. The argon was a lot heavier.
Also seriously doubt the bottle would blow up. I'd think the yeast wold probably die off with less pressure then needed to rupture the bottle.

if you add too much sugar and yeast the thing will blow at least the cap blew off. found that one out the hard way, made it while puffin on a j, forgot to make a hole for the gas to escape then left it out luckly it was in the garage at the time.
I need to know about pressure,So i DONT blow anything up. I have 34 years experience working in the plumbing and piping indursty. Ive worked on all sorts of piping systems, alot of them were high pressure systems dealing with various gases. I know how to weld, ive used argon, for welding and purging, also dewars full of liquid nitrogen.This is a DIY fourm, the system I wish to build is just like a standard tank system, with a regulator and a solenoid. I have a empty "b" tank and a flow meter I can use. Instead of having to keep going to the welding supply to get my tank refilled, Id like to set it up so i can make my own co2, in my tank. I would be a fool to build such a system without knowing what type of pressures I'd be working with. I did find some info at a wine making web site. In the making of champange they add a little yeast, sugar, and juice to the wine before they bottle it . This causes secondary fermentation in the bottle, which gives champange its bubbles. According to the article this secondary fermentation builds about 90 to 100 lbs of pressure. Thats why the cork pops! The article also states that a WEAKER ratio of YSJ will result in less pressure 60 to 90 lbs, this is called sparkling wine. All that being said. I just want to make sure I don't build some kind of bomb that blows up my house. Obviously I can get 100lbs, but how much higher will it go? I think somebody who does a lot of home brewing might have my answer. Thanks for all your help and input .

This was the DIY Co2 format i followed. I only used a bigger container.

Iam more worryied about the smell made from the suger water and yeast. I know that beer making is very smelly. Alot of CO2 is released with a 5 gallon batch of cooled suger water and a few 100ml of yeast. The bottle must be vented and if the hose gets blocked the top goes flying off. I say just do it the right way if you wish to use CO2.

shows how much co2 is being made by home made co2....YouTube - My C02 SYSTEM
Guys you are telling me things I already know. I AM trying to do it right. I would never build a pressure building system with plastic bottles ,or a gas can. I have gas bottles, I have a regulator and flow meter. Ive been building gas delivery systems for 35 years. Im a plumber not a chemist. All I want to know is how MUCH pressure yeast, sugar and water is capable of making. As far as the smell, I live 2 blocks from a beer brewery, and peoplearound here are used to the smell of beer all the time.
Well thanks for your input and trying to help.
