12' Wort Chiller?
 
Would a 12' Stainless Wort Chiller be efficient enough for a 5 gallon setup in a kitchen sink?

Yes.... IMO

It'll be better than nothing.

Stir it a lot while you're cooling, and you should be fine.

This time of year, you'll be fine because of the COLD tap water...but if/when that warms up you may have to wait a while for the wort to get down to pitching temp. Not sure about CT in the summer, but around here our tap water get's up to 85F.

Do you have a good deal on stainless because copper transfers heat better. I know some people dont like the copper, but I have a 15ft copper chiller and it works great. I have one of those big blue tubs for kegs, I put my brew pot in there, then I hook my hose to the chiller, then use a small piece of hose from the discharge into the tub. Then I use another small piece of hose to siphon out of the tub onto the ground. With the hose at 3/4 the disharge is still pretty cold, so the water in the tub cools the outside of the pot as well. Kind of a 2 stage cooling system.

EDIT: I just reread you post and saw it was in your sink, so my setup wouldnt work, but I think copper is still better for heat transfer.

OK, I've got to do it now.

Sometime this weekend I'll do the calculations for convection on the inside and outside of a chiller and set up the resistance network to show how minimal the higher conductivity of copper matters. It's all about the convection guys.

BTW, this is ALL I thought about through my entire heat transfer course I just finished up.

Be sure to factor in the dramatically thinner walls of stainless tubing. I've got both a copper and a stainless chiller of about the same size...the stainless is a fraction of the copper ones weight, light as a feather. Both seem to work about the same.

Of course lemon but...

It is possible that the extra thickness of the copper benefits heat transfer. How? More surface area. I wont know until I crunch some numbers to give me some realistic convection rates.

Case in point, contacts actually cool your eyes. They insulate some conduction, but they create an increase in surface are for convection.


But anyway I will probably use 32 thou for the copper and 20 for the SS.

How do thicker walls get you extra surface area? Given the same OD, thinner walls would actually translate to slightly more surface area on the inside.
