Talk:Orders of magnitude (pressure)

pressure washers
It seems a bit inaccurate to definitively state that all pressure washers function at the same pressure. Can we get a fact check, or better a range/clarification of this datum? -- nae'blis 02:45, 15 August 2006 (UTC)

Degenerate matter
I think it would be useful to include the pressures at which various degenerate matter effects dominate, i.e. electron degeneracy, neutron degeneracy, quark, etc. These values would not be of much practical use, but would illustrate the relationship of quantum physics effects to everyday life. —Preceding unsigned comment added by 130.76.23.45 (talk) 21:01, 12 February 2008 (UTC)
 * I second this. Was looking for the pressure at the centre of a neutron star.  — Preceding unsigned comment added by 130.246.132.178 (talk) 18:55, 30 June 2011 (UTC)

Housefly on a postage stamp?
I ditched this example because it seems wrong. A housefly weighs about 10 mg to 12 mg  and I just measured a standard, non-commemorative postage stamp at 20 x 23 mm. Google Calculator tells me that "10 milligrams * 9.8 metres per square second / 460 square millimetres" = 0.213043478 pascals. I haven't taken account of buoyancy, which would make the pressure even less. To get 1 Pa you would need a very big fly or a very small stamp. --Heron (talk) 14:10, 23 March 2008 (UTC)

Fictional Character. Stupid to include this.
I'm removing this: 12.7 MPa	1850 psi	Pressure exerted from a punch by Ivan Drago in Rocky IV Davidmanheim (talk) 16:04, 12 May 2010 (UTC) I disagree.Arctic Gazelle (talk) 08:19, 20 April 2021 (UTC)

Near Earth outer space pressure
How can the 'Near Earth outer space pressure' be over 10,000 times as high as the pressure of the atmosphere on the moon?? —Preceding unsigned comment added by 82.71.43.37 (talk) 19:22, 18 May 2010 (UTC)

Industrial Processes
There's an order of magnitude gap between 600 MN and 9 GPa. There's no mention of industrial high-pressure processes such as die-cutting, punch cutting, or the pressure between two rollers, such as used to thin aluminum ingots. I don't know any of these pressure values, but certainly someone does. Mathwhiz90601 (talk) 18:39, 9 October 2010 (UTC)

Perfect vacuum
According to the Heisenberg principle of uncertainty, a perfect vacuum cannot exist in our Universe. therefore I am removing the entry from the table. See vacuum energy. — Preceding unsigned comment added by 190.224.189.251 (talk) 09:19, 9 November 2012 (UTC)

High-heel-presure
it's the wrong line, should be between 4 and 10 MP according to the source in the link and the physik (A=0,006 sqm). JOberst (talk)

Pluto
The pressure figure for Pluto (~200 mPa) is from 1988. It should be replaced by a more recent, more reliable figure, now that New Horizons has flown by Pluto.--Solomonfromfinland (talk) 20:10, 30 December 2015 (UTC)

External links modified
Hello fellow Wikipedians,

I have just modified one external link on Orders of magnitude (pressure). Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:
 * Added archive https://web.archive.org/web/20071014041459/http://leverguns.com/articles/saami_pressures.htm to http://www.leverguns.com/articles/saami_pressures.htm

When you have finished reviewing my changes, you may follow the instructions on the template below to fix any issues with the URLs.

New Horizons pressure estimate
Someone who can do the table formatting better than I can should update Pluto - 1 Pa as measured by New Horizons. Appropriate references, from infobox on Pluto: 174.21.106.41 (talk) 08:39, 22 April 2018 (UTC)

supernova explosion
What kind of pressures can be produced in supernova explosions? — Preceding unsigned comment added by Greg.collver (talk • contribs) 16:40, 11 May 2018 (UTC)

The Planck pressure (4.63×10^108 bar)
I suggest both to Actualy nor from the linked page, which has no references to any pressure, nor the note explain much the meaning of the subject. --79.18.130.247 (talk) 05:40, 11 June 2020 (UTC)
 * adjust the link
 * explain in more details what is it

How about mentioning (some) vacuum chambers?
There's no mention of any vacuum chambers, e.g. the biggest vacuum chamber in the world. Arctic Gazelle (talk) 08:17, 20 April 2021 (UTC)

Distinguish regimes and add mean-free path
It would be nice to have delimiters for HV, UHV and XHV. Also, add a column indicating the mean free path of molecules in air (N2) — Preceding unsigned comment added by Rolancito (talk • contribs) 13:45, 2 December 2022 (UTC)

Figure for the moon contradicts Wikipedia page on the Moon
the night time surface pressure is listed in the lead on the page for The Moon as 10^-10 pascals. But is listed as 10^11 here. Likewise, the daytime pressure is listed here as 10^10 pascals in this table, but the Wiki for The Moon lists it as 10^-7.

My guess is whomever put these figures in may have flubbed the decimal placement. Without actually converting the units myself.

I would love to fix it, but quickly realized that would require completely rearranging the table. Which is beyond me. VoidHalo (talk) 19:01, 15 January 2024 (UTC)
