If this was worn, how would thermodynamics factor into this?
Would the beer cool you down to the extent of hypothermia? If the cheap lager is say, 2°C?
For ease, the ambient temperature is 21°C
What’s a body’s skin temp? 14°C or so?

I guess that heavily depends if you skin stays dry. Condensation might be an issue so this depends on ambient temperature and moisture.
On the heat transfer I guess you would stop getting colder as soon as temperature equilibrium is reached. That heavily depends on ambient temp. I guess the beer is not so much volume that you body can’t warm that up assuming you have enough calories available.
Thanks for actually reading the question and answering.
Can’t be all anti AI extremists. ;)
An adult generates about 100watts of heat. Assuming 5l of beer, heating it up from 2 to 21 degrees would require 110wh of energy. So I don’t think you’d suffer hypothermia, just be pretty cold.
BTW race drivers use chill vests and they don’t have a huge effect temperature wise.
The vests can have a strong effect, but aren’t those using a cooler and a pump to have continuous flow?
I’ve used similar devices and on full flow they will cool your ass down, pronto. I’ve had to turn the pump down to it’s lowest setting.
Of course that’s using ice in the cooler, which I assume race drivers have.
Sambucha actually bought one of these, filled it with iced tea, and put it on. IIRC, his main complaint about it was the weight. Also, the straw was finicky and he spilled a good bit of tea all over the place.
Normal human skin temp is between 33 and 37 °C
To get hypothermia baked the ambient temperature needs to be pretty low or you need to be exposed for it very long or you need to be impaired in your heat production capabilities (mostly due to drugs). This is faster when you are in a more solid medium( mist or water). As a common knowledge example the ppl that hit the -2°C water on the Titanic died in 15-30 mins due to hypothermia. 10 liters of cold water will most lily not be enough to cause hypothermia except if you are on drugs or old age.
