Well, after some more searching I found a formula that will tell me what pressure to set if I want a specific volume of CO2, and in turn from this I was able to get the grams using another formula, now onto the next step, getting the volume from Temp and pressure: T= Temp in degrees F V =...

I just called them up (508 721-2226) and talked to Bob, They are still located at 97 Bancroft Street in Auburn. And the price for a swap is $20 for a 20Lb tank. He was very nice on the phone as compared to the other shop I called in boyleston (The Homebrew Emporium on Steryling street) The first...

Thank you, I will have to call them up, if not then its to try a welding shop somewhere. Thank you for that info too, I will be looking for them online too to compare prices and locations to where I live, not that I will (well maybe - Wife drinks ALOT of coca cola) refilling that often, but...

Here is what I have so far: Lets say the pressure is 45 PSI (3.0612 atm) and the temp is 20 C. C= Concentration of the dissolved gas in the solution Kh = Henry's Law constant for the solution P = Partial pressure of the gas above the solution P = 3.0612 atm Kh (This s=is where I would need...

I have been searching all over and keep seeing the Henry's Law but I cant seem to get a formula together for what I am looking for. I want to know how many grams of CO2 are in the soda based on the temperature of the soda and the pressure of the headspace (at equilibrium when no more CO2 is...

Hi all, sorry to bring this back up. I am also looking at finding a place to refill a 20Lb tank, I have tried to call AirGas in Worcester but was unable to get through to someone. Does anyone have a number that I can contact for their retail section about pricing on refills? Are there other...
