What is an example for _not_ reversible? (in statistical mechanics, not quants)

For sure? What about the average over time (ergodicity)? In statistical mechanics temperature is an average kinetic energy.

I have an interesting(IMHO) approach to explaining how the vortex tube works. There are a few explanations on wiki, but not a simple and convincing final one. https://en.wikipedia.org/wiki/Vortex_tube Normally a vortex tube, that runs well, howls very loud. It is a kind of aerodynamically...
