But specifically on velocity in superfluids or superfluids aka BEC Bose-Einstein Condensates,
This model predicts the multi body gravitational motions of the planets including the perihelion of Mercury and also vortices in superfluids:

This model derives gravity from the Standard Model of particle physics:

And this model describes all in terms of consistency maximization

> Abstract: We derive the complete structure of fundamental physics from a single principle: Quantum coherence maximization under self-consistency constraints. [...]
And this model describes all terms in terms of Consistency Functional K; https://news.ycombinator.com/item?id=45909513 :

\delta\mathcal{K}(\rho, g) = 0
And Wolfram has a unified theory, too
What are the limits to model unification?
