If you take a 1/2" input and split it into three 1/2" tubes, your only going to end up with 3 tubes 1/3rd full of water no? So your only ending up with 1/3rd of each tube diameter actually chilling...which doesnt seem any more efficient than just having one 1/2" tube having water contact around the entire outer diameter of the single tube. I suppose if you could guarantee that that 1/3rd amount of water going into each tube is only coating the outer wall of the tube leaving a hollow area in the middle you'd see better cooling...
Or am i missing something?
A couple things here.
First, its fed with a garden hose (5/8") into a 1/2" piece of copper, which feeds 3 3/8" tubes. A 1/2" tube has about twice the area of a 3/8" tube, so you're not losing much there.
Second, water (wort) contacts each tube all the way around. None of the tubes touch each other.
I'm not an expert by any means, but it seems to me that three shorter runs are better than one longer run, the reason being that the heat transfers pretty quickly. With three shorter runs, you are getting a larger volume of colder water, and ejecting the hotter water quicker.
That aside, my pot is 19" in diameter and only 12" high. One 60' tube would leave a good deal of the tubing above the wort, which is obviously bad!
Regardless of the theory, in practice it works really well. Like I said, went from boil to <65 in under 5 minutes. I'll time it next time.

Not sure why people think this is hard to clean? Soak it in some hot water you collect from the cooling process, hose it down, you're good!
