Not sure I completely follow, but the butter will not slide uphill once it gets a layer of melted butter beneath it. In your...

The butter is experiencing a force ( frictional) that is holding it in place against basically imperceptible elevation gradient ( a...

I don't think that the motion of a pat of butter has anything to do with thermodynamics, that will just be Newtonian mechanics. That...

Exactly my point. There is nothing inherent in a blip that makes it distinguishable as a particular phenomenon...it becomes...

You're missing my point. I'm not arguing the models are limited by what we can directly perceive by sensory input. Let's look at UV. We...

Since everything "found/examined/observed" in the physical world is mediated by the mind; At a fundamental level it actually is the case...

If it doesn't exist, how do you suppose it works so consistently on such deep levels? All of these things that you say "do exist", are...

I got Chat GPT to look at the Fluid Mechanics approach. After it fixed a sign error i made in the flux term It gets what @haruspex, and...

as far as I can tell that is what is happening. The bottom temperature is leading during the transient phase while a significant the...

It's not difficult, but I do recall "getting it"(I learned algebra mostly as an adult though). I teach my kids by balance scale type...

The vertical pipe is the discharge. If there is a check valve at its base, we don't have to worry about dynamics of the flow into that...

If there is doubt, couldn't we just compare the cited pump head of manufactured ram pumps to the theoretical ## \frac{\Delta p}{\rho g }...

I know the feeling very well. :smile:

Okay, I stand corrected. Had been thinking about it and realised that, yes, there needs to be a moment of negative pressure for the...
