So I live on the Northern Pacific and have been tearing into the electrical and water systems in my boat lately. While I was cursing loudly and wedged in the bilge yesterday, I had the totally impractical idea of installing a mount and tap for my beer keg system on my boat.
The keg/CO2 mount and tap handle are all easy enough; brace them low and out of the way and run hose to the cabin. But a cooling system is a little tougher. Refrigerator is not possible in the space I have. I've been kicking around the idea of buying a counterflow chiller to run cold raw salt water through against pressurized brew. I'm not sure the cooling I'd get is worth cutting two extra holes in the hull. An example of one of these is here - http://ift.tt/2fLMQEM
No idea what type of thermal transfer equation I'd need with counterflowing liquids or any coefficients, but I'm hoping someone here can help me in the right direction and maybe see if it's worth taking on.
Outside hose (Seawater) - 15.87mm dia (7°C)
Inside hose (Beer!) - 9.52mm dia (20°C)
Hose length - 7.6m
Pump pressure is roughly 2.75 bars
Keg pressure is roughly .82 bars
It might be a long shot and probably not the normal question, but I appreciate any help you guys or gals could give me!
