DIY CO2 system question (Correct calculations)
I took out my magnifying glass and my daughters plastic ruler and came up
with the opening at .4 cm. So redoing the math you put forword (thank you by the way): volume=4/3*pi*r3 ..4 cm opening creats a bubble of (4/3*3.14159 * (.2*.2*.2) = .0335 cm3 and the number of days: 44800 cm3/.0335cm2 = 1336902.6 bubbles then at 1/sec = 15.5 days Of course this assumes all CO2 is released. All sugar is converted and the yeast does not die in its own creations. But it does say that the maximum it will last at 1/sec is 15 days. So depending on tempature the rate of production can be changed. thus changing the length that the generator will work. This of course is avoiding the discussion of the other variables of alochol posioning of the yeast and CO2 concentration in the solution. As the great philospher Col. Klink said "Very Interesting". Thank you for the information, it definitly helps me understand what is going on. Ken Useful: http://grapevine.abe.msstate.edu/~ft...tor/index.html "Harry Muscle" wrote in message ... "Ken Pinard" wrote in message ... Ok, now I am getting even more curious, Do you happen to know the volume of 2 mols of CO2? How about the volume of single bubble from a 1/4" (standard) air line? Yeh, I've gone off the deep end. I was just thinking that I might be able to guess the length that a solution could survive and how much CO2 would be available for the tank during that time. Basically, the it won't change the how often I change the bott , ut I started in Chemistry in college because I found the numbers intriguing. Thank you again, Ken Pinard 1 mole of CO2 occupies 22.4 litres of space, so 2 moles would be 44.8 litres. The volume of a bubble with a diam f 1/4" (0.635cm) is 0.134 cm2. So 44.8 litres is 44800 cm2 divide that by 0.134 cm2 you get 334328.36 bubbles. 44800/.0335 = 1336902.6 bubbles at 1/sec = 15.5 days Hope that helps, and let me know if I made any mistakes. Harry P.S. I double checked my math and it seems alright, but I'm curious if there's some mistake somewhere, cause that many bubbles, at 1 bubble per second would only last about 3-4 days. It might have something to do with the fact that bubbles from 1/4" tubing will be smaller than 1/4". -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |
