I own a Bing's Favorite, and I thoroughly enjoy smoking it.
I'm a little skeptical of this claim, Checotah. This has been discussed before, but I'm not sure that smoke would be noticeably cooler after travelling an extra inch (at most) of stem.
Any physicists out there?
As a matter of fact, I study physics :P Fourier's law of heat conduction states that the heat flux (the amount of energy transferred per unit time per unit of surface area) depends on the physical characteristics of the ''barrier'' through which the heat is conducted, and is proportional to the temperature gradient across the barrier.
Let us assume (just for a 'back-of-the-envelope calculation') that you draw smoke so that it travels with the same velocity regardless of the length of the pipe. Let us also assume that the stem maintains the same average temperature regardless of length (this is, of course, only approximately true). In that case, the total energy transfer per unit of time ("power", in the technical sense) is proportional to the area of the pipe stem, and thus proportional to the length of the stem. In that case, the energy dissipated through a 14cm stem is 1.4 times that of a 10cm stem (just rough measurements of my two nearest pipes).
My personal experience is that long-stemmed pipes smoke somewhat cooler, even if it's only a difference of a few centimeters.
