Confusion About Gravity

I'm confused why gravity alone couldn't just do the siphon effect. Let's think about it in two forms: We have a bowl, and we have a tube. We put water in each. The bowl is the control specimen. The tube is the experiment specimen. The shape of the water is different: gravity pulls the water down equally and creates a flat top of water in the bowl. If you tilt the bowl, the water stays flat on top, gravity pulling it down across the surface. It's normal behavior. Now imagine the water inside this tube. Luckily, it is in a U shape, so the water moved through the tube and forms a flat top... just like the bowl, just like gravity should. Now, if the water is not level, it moves to become level like normal: Here the water tries to make it's flat top due to gravity but oh no! at this point in time it is not equal, so just like the bowl, the water moves. The water is moving away from one end of the tube.... the air rushes in. The siphon is live. All thanks to gravity! BTW Pascal's bowl is just sitting there in another liquid, so gravity is just holding the flat top in the bowl. Pascal can use the tube shape, but it's still gravity flattening out the water due to gravity. Got it? — Preceding unsigned comment added by 75.162.28.226 (talk) 02:49, 28 February 2023 (UTC)[reply]

Improper usage

A Google search reveals that siphon is occasionally substituted for search, browse, or rifle: “he quickly siphoned through the papers in the drawer.” This meaning is not found in any dictionary I have consulted, even as an alternate or rare definition. It might be useful to mention this misappropriation of the word.Roricka (talk) 05:29, 24 January 2023 (UTC)[reply]

That's odd. I have a feeling that those might just be mistakes rather than meaningful contributions, unless it's obvious that the ordinary meaning of "siphon" was intentionally being used (metaphorically) to describe someone's action.

Otherwise, I can just start saying "hat" when I mean "table", and the mere fact that I've done that will force everyone to document my new usage. :) TooManyFingers (talk) 18:07, 23 August 2023 (UTC)[reply]

Bubbles that "break" the siphon

In the section on using Bernoulli's equation, subsection "Maximum height", it says this:

if the bubbles enlarge to fill the pipe then the siphon will "break"

Which should it say: "fill the diameter of the pipe"? Or "fill the length of the pipe"? TooManyFingers (talk) 17:53, 23 August 2023 (UTC)[reply]

How is Vb = Va in the siphon, in the Bernoulli section
