(wp:RS)[edit]

Bejan numbers seem to have been published in Thermal Science, from Serbia, which is hardly a prestigious journal. — Preceding unsigned comment added by Prodx3 (talk • contribs) 02:58, 8 February 2015 (UTC)[reply]

Why not separate articles?[edit]

I'm not proposing a split, but the fact is that the colleague has failed to clarify why these various dimensionless ratios bear talking about as a single topic. I presume from one of B's previous works that this is about self-organizing systems of varying dimension behaving analogously, and probably i could have read more deeply, but our colleague seems bent on shaping the topic without sounding like they know enuf about it to do so.

Δp (undefined variable)[edit]

Δp is used repeatedly in this article without being defined. Is this change in momentum? Is this change in pressure? I don't know. Not defining variables because their meaning seems obvious to you is the easiest way to turn useful equations into useless garbage for readers. Someone who knows what this variable means should define it in the article. Same for any other undefined variables. DubleH (talk) 10:20, 7 June 2021 (UTC)[reply]
