Vacuums
[edit]Vacuums do actually attract matter; matter is pushed into them by the higher pressure of surrounding air. Why is it that matter is pushed into vacuums, not pulled? All your base are belong to us 09:33, 31 May 2005 (UTC)
- Because there is nothing in a vacuum to do any pulling :) Kappa 09:39, 31 May 2005 (UTC)
Aha, of course... Thanks! All your base are belong to us 09:45, 31 May 2005 (UTC)
Why does suction happen ?
why suction port always larger in diameter than pressure port (In case of hydrulic pumps)?
"Gers"
[edit]What is "Gers" in relation to suction?
Should it be "gears"? Or, is this just some Gersois vandalism?
Thank You
[edit]Thanks to this article I now know that סניקה is "discharge". —Preceding unsigned comment added by 62.90.140.59 (talk) 11:26, 29 November 2009 (UTC)
Sample video
[edit]The sample video does not demonstrate a vacuum from suction (see video description). Not sure what to replace it with. 62.232.179.170 (talk) 10:37, 24 September 2018 (UTC)
Suction does suck
[edit]This page has multiple references to suction not sucking. Obviously that is wrong. While it is valuable to say that sucking/suction is caused by pressure from a fluid pushing on an object, not pulling on it, it is incorrect to say that suction doesn't suck. Sucking is creating a partial vacuum in the direction you want an object to move. When air is "sucked" into the lungs, a partial vacuum is created causing ambient air pressure to push air into the lungs. During uncontrolled decompression, objects are "sucked out" when they are pushed by air pressure toward a relative vacuum. In fact, the page contradicts itself. In the caption, it says that by convention, "sucked in" means to be moved from ambient pressure towards a low pressure zone. Obviously, that is what is happening during uncontrolled decompression. The source for that paragraph about the semantics involving uncontrolled decompression is an article on Quora. This is not a reliable source. Anybody can write anything on Quora. And the 2nd reference is another article referencing the first. I made one correction yesterday which seems to have been reversed. I changed, "Accordingly, from a physics point of view, the objects are not sucked but pushed." to "Accordingly, from a physics point of view, the objects are not pulled The way I put it was correct. from a physics point of view, when an object is sucked, it is pushed, not pulled. Still, it is sucked. Jheim.math.wisc.edu (talk) 18:59, 17 February 2025 (UTC)
