Greetings all!
I have a question for you all regarding oxygenation of wort. I have a friend who works in a brewery in which they oxygenate inline from the wort chiller to the fermenter with pure oxygen (which seems to be the standard practice nowadays) . He said that on average, for standard gravity worts (10 to 12 plato), they use 8 litters of O2 per barrel of wort, which then allows them to calculate the flow rate in litters per minute from their oxygen source.
total barrels wort * 8 l/bbl O2 = total litters of O2 needed
total litters O2 / knockout time (in minutes) = flow rate of O2 in liters per minute
My question is this: with most professional brewing texts out there saying that you need 8-10ppm (or 8-10 mg/l) of O2 total (for standard gravity worts), how does one get from mg/l to l/bbl? I've attempted to do all of the calculations numerous times, but just can't seem to figure out how to get from mg/l O2 to litters O2. On top of that I still can't figure out how they figured out how to use a metric measurement in conjunction with a US barrel.
Any help/explanation (or even a point in the right direction as far as a text/lecture) would be greatly useful and much appreciated!
Cheers!
