Talk:Siphon
From Wikipedia, the free encyclopedia
Not all liquids boil under vacuum. That should be changed. It's true that water will. Ashi_Starshade
Can siphon also be used for U-bends that go below the level of the reservoir? Syd1435 01:27, 2004 Nov 25 (UTC)
- If I understand you correctly, that's an inverted siphon described in the article and it's not a siphon at all.Samw 04:33, 25 Nov 2004 (UTC)
The article says:
- The siphon was first used as a weapon by the Byzantine Navy, and the most common method of deployment was to emit Greek fire, a formula of burning oil, through a large bronze tube onto enemy ships. Usually the mixture would be stored in heated, pressurized barrels and projected through the tube by some sort of pump while the operators were sheltered behind large iron shields.
If this uses "pressurized" barrels and "some sort of pump", is this really a siphon?
- See siphon bottle in the article. I didn't write this so I can't vouch for it's historical accuracy. But physically, it would be a siphon. The extra pressure in the barrel would make it a siphon bottle.Samw 04:09, 2 Dec 2004 (UTC)
The writer of this article has referred to vacuum in two instances. The first claims that flow of liquid creates the vacuum. later on gravity tends to draw the liquid down in both directions creating a vacuum. I would suggest that "flow of liquid" eliminates all the air and so the liquid flows. When the upper end of the pipe is exposed air immediately invades and breaks the siphon. Thus I believe that references to vacuum should be deleted. Jack hill 7 Jan 05.
- You are correct, there is never a vacuum formed and there is never any air within the siphon or it will not work. I see how the current description can be misleading. The reference to a vacuum is simply explain how the siphon works. If you have a better description, feel free to rewrite that section. I tried without success. Samw 04:14, 8 Jan 2005 (UTC)
A lot of biology articles refer here, but the biological use of the word is really quite distinct. Unless anyone objects, I propose to take out the biological section (except for the discussion of the siphon effect in biology) and create a new entry for the siphon in invertebrate anatomy.

- I had a disambiguation at the top of the article just for that reason until it was removed on Nov 28, 2005. I would support you adding it back in. Samw 00:45, 23 February 2006 (UTC)
[edit] Mathematics
I originally added the math section at the end because the general reader of a general article like this isn't likely to be familiar with Bernoulli's equation. I'm merely applying the principle of progressive disclosure. Any objections to me moving the math section further down the article? Samw 03:19, 7 May 2006 (UTC)
I made an error in the discussion and erased my comment.
