"The energy of the falling water entrains the air into the water, but is not the energy that pressurizes the air as is often incorrectly sighted. That is solely a derivative of the hydraulic head". I am certain that the energy from the falling water IS the energy that compresses the air. No other energy enters the system. Given that the energy from falling water powers the system it must be the energy that pressurizes the air. I am certain that the text that I have in brackets in the article needs to be reworded. I am not qualified to word it. Brian Gaiatechnician (talk) 02:29, 31 March 2009 (UTC)

I'm not too happy with this either. First off, "the energy of the falling water entrains the air into the water"; how is one supposed to interpret this? are we talking about the kinetic energy, the change in kinetic energy, or the change in potential energy? Hydraulic head is ambiguous as well, there's velocity head, pressure head and elevation head. It may be better to remove the statement, or include a more detailed qualitative and quantitative explanation; I doubt a simple model would suffice, given that the air moves (upwards) relative to the water, the density of the mixture depends on the amount of air mixed with the water and the height of the water column, since the air is compressible, and so on. BTW, it should be cited, not sighted.

The paragraph about the humidity of the air could also use some additional info. It's true that warming the air would lower the humidity, but on the other hand, one starts off with air at 100% humidity. I think the effect of isothermal expansion would be more important if one wants to obtain very dry air. The change in relative humidity in function of temperature has in itself nothing to do with the fact that the air is compressed in this case. Ssscienccce (talk) 17:21, 24 May 2012 (UTC)

<years later> It doesn't matter how far the water falls *down* with air bubbles in it, what matters is how deep the separation chamber is below the surface of the discharged water when it reaches atmospheric pressure. If the separation chamber is only 50 feet below the discharge waterway, you could get only about 21 PSIG air pressure out of the system, no matter how far the water with entrained air fell on the way in. --Wtshymanski (talk) 00:42, 20 May 2017 (UTC)

Why remove the artificial trompes section?

Hello. I'm not sure how to reach Wtshymanski so I'm adding an edit here. After hard work trying to improve the knowledge of the Trompe, I've come back to see my edit reverted and knowledge suppressed. I see that you are a member in good standing and experience. Based on this interaction, I realize I no longer wish to contribute financially to Wikipedia. Instead of helping me make a useful contribution, you have reverted an edit with important new information that wasn't in the original article. This is unfortunate and I feel it best to spend my resources elsewhere. In this era of insanity, we should work together to bring light to the world, not suppress it. — Preceding unsigned comment added by Oyamist (talk • contribs) 16:29, 21 March 2020 (UTC)

Yo, Wtshymanski -- I agree with Oyamist: Your wholesale removal of their section on artificial trompes feels like rather a dick move. Why? And why just like that, without even engaging in any dialogue here at all? It added useful and interesting information. --CRConrad (talk) 11:37, 9 June 2021 (UTC)

All trompes are artificial. The section deleted back in March 2020 was unreferenced and did not appear to discuss the subject matter of this article. This is not a venue for publishing original research. Observe the notice given every time an edit is saved that the results will be ruthlessly (at times) edited. --Wtshymanski (talk) 00:37, 13 June 2021 (UTC)
