comment Child-Langmuir Space Charge Law for Non-Zero Cathode Potential (Non-Zero Initial Electron Velocity)
These formulas might be attempts to combine two effects: 1) the actual anode-to-cathode accelerating voltage potential $V_{AK}$, which can only depend on the difference between the two potentials, 2) an "effective" (e.g. fake) cathode potential $V_{eff}$ that models the initial velocity of the electrons that are "boiling" out of the heated cathode.

revised Homemade salad dressing separates into layers after it sits for a while. Why doesn't this violate the 2nd law of thermodynamics?

I very much like your approach, and agree with your conclusion, but think one detail is a bit off. See my answer.

comment What is $vdp$ work and when do I use it?
Nice, thanks. I think the point of the answer by Bryson S. is that $H_{exit}=H_{entry}-W$ for an adiabatic process, where $W$ is the (positive) work output of the shaft, so $H$ decreases as shaft work is performed.

comment Is there a compound denser than the densest element?
As a rejected edit noted, osmium forms toxic osmium tetroxide when exposed to the oxygen in air (ref wikipedia). Do not suggest it!!!
