I am an engineer learning physics in my spare time. My current focus is quantum field theory and the Standard Model.

@JeffDror: ahh, indeed, that's exactly that.

@JeffDror: actually I had misread your answer. It's fine.

Could you expand your explanation on the example with reaction 2? I'm not clear on how the initial and final isospin states are calculated.

comment Which temperature to evaluate fluid properties in pipe?
Usually, when the temperature does not change too much, the Nusselt number is estimated by taking the average properties between inlet and outlet. A correction factor is then applied as you describe to compensate for the temperature gradient at the wall. See for example the Sieder-Tate correlation in en.wikipedia.org/wiki/Nusselt_number

comment What is the physical basis behind thermal diffusion in a Clusius-Dickel column?
Thanks. Could you point me to a reference that works out the details?
