**Re: Passive CO2 diffuser** I just read that temperature and pressure influences the rate of gass diffusion into water. The gass chamber is naturally high in pressure so CO2 diffusion should be greater than 1 atmospheric pressure. How much more specifically I don't know. I'd need to find a pressure gauge and a formula to calculate.
Once the chamber is filled with pure CO2, I guess I can time how long it takes for the volume of CO2 to dissolve into water. |
