I have aquired a carbonation chart to use at 6000 ft which is appropriate for our brewery here in the mountains. We use it to determine the volumes of CO2 in our beer. It is similar to the sea level carbonation chart but slightly different in numbers. I have been using this sheet since I began here and I am wondering if anyone knows anything about correction factors and elevation involved in carbonation. At the top of the sheet it reads:
Atmospheric Pressure 11.69
Correction Factor 3.01
Now, I know that atm pressure at sea level is 14.7. So this makes sense that 11.69 plus 3.01 equals 14.7. How then is 3.01 a function of 6000 feet above sea level?
What I am trying to do is to expand and redevelope the sheet for reading vol CO2 at certain pressures and temperatures. I currently have only 45F up to 20 psig. This is for Zahm Nagel testing. Sometimes our beer reaches 50 F and then I begin guessing at the vol CO2. I have tried to enter the data into a spread sheet, however it does not understand the sequence of numbers as they are not consistant. If I understood the method behind the madness then I might be able to design the sheet myself. All comments would be helpfull.
Brew On!
