First try with this vessel. (6 gal thin neck glass carboy)
Wish me luck friends! Hope I don't wake up to a boom and a mess!
Also, has anyone had this go wrong? I've read up quite a bit online and can only find accounts of people not willing to risk the implosion and accounts of people who have always solid bung'd. I couldn't find anyone who reported an actual implosion haha. I partially posted this so it could join the documentation of solid bung glass vessel cold crashing after all the research I've done on the topic.
My amazing room mate estimated the volume of the gas at the top of my fermenter as a cone, its got .001473m3 space. And if you put that much space through the ideal gas law equations for a temp change of 68f to 46f the psi change is only ~0.488. Since my fermenter lid is less volume than its conical estimation, it's actually even less pressure. The write up is attached as a file.
I believe the thin neck of my fermenter will be more than sturdy enough to withstand a negative change in pressure of 0.5 psi. I'll report here tomorrow how it all works out.
Next Day Update: No implosion! Woo! I will be doing this again in the future. If you vote yes on having an implosion can you specify when the implosion happened? Like if it was while you were moving the vessel w/ negative pressure?
