Pascal



The pascal (symbol Pa) is the SI physical unit of pressure. It is equivalent to one newton per square metre. The unit is named after Blaise Pascal, the eminent French mathematician, physicist and philosopher. ; 1 Pa : = 1 N/m2 = 1 (kg·m/s2)/m2 = 1 kg/m·s2 : = 0.01 millibar : = 0.00001 Bar (unit) The same unit is also used for stress (physics), Young's modulus and tensile strength. Standard atmospheric pressure is 101,325 Pa = 101.325 kPa = 1,013.25 hPa = 1,013.25 mbar = 760 torr (ISO 2533). Meteorologists world-wide have for a long time measured air pressure in millibars. After the introduction of SI units, many preferred to preserve the customary pressure figures. Therefore, meteorologists use hectopascals today for air pressure, which are equivalent to millibars, while similar pressures are given in kilopascals in practically all other fields, where the hecto prefix is hardly ever used. ; 1 hectopascal (hPa) : = 100 Pa = 1 mbar ; 1 kilopascal (kPa) : = 1,000 Pa = 10 hPa In the former Soviet Metre-tonne-second system of units the unit of pressure is the pieze, which is equivalent to one kilopascal. The Unicode computer character set has dedicated symbols ㎩ for Pa and ㎪ for kPa, but these exist merely for backwards-compatibility with some older ideographic character sets. == Examples of various values (approximately) == (See SI prefix for guide to units.) {| border="1" cellpadding="1" cellspacing="1" | 0.5 Pa | Atmospheric pressure on Pluto (planet) (1988 figure; very roughly) |- | 10 Pa | Pressure increase per 1 mm of a water column¹ |- | 1 kPa | Atmospheric pressure on Mars (planet), ∼1 % of atmospheric sea-level pressure on Earth |- | 10 kPa | Pressure increase per 1 m of a water column¹, or

My major interests: Chess, Geography, History, and Rock_and_roll Music. ==images on ifd== The images :Image:Virgin islands sm02.jpg and :Image:British virgin islands sm02.jpg have been listed on Wikipedia:Images for deletion. They have been obsoleted by :Image:Virgin islands sm02.png and :Image:British virgin islands sm02.png. Since these images were uploaded by you, you might want to go through the process of re-downloading the original GIFs and converting them to PNGs, then changing over the links and listing the old JPGs on Wikipedia:Images for deletion, as I've done here. I'll fix them as I see them. User:Grendelkhan 04:44, 2004 May 12 (UTC) Ditto for :Image:Kenya sm02.jpg. (If you don't want these notifications, let me know and I'll stop leaving them; I figured you might want to know where all your images are going.) User:Grendelkhan 05:25, 2004 May 12 (UTC) * :Image:Montserrat sm03.jpg * :Image:Cayman islands sm02.jpg User:Grendelkhan 16:53, 2004 May 12 (UTC) :Its OK User:Pascal 21:41, 15 Jul 2004 (UTC) ==WikiProject Unrecognized Countries== Hi Pascal, I noticed you had made contributions to Anjouan. If you're interested in Anjouan and similar places, why don't you drop by the Wikipedia:WikiProject Unrecognized countries and help add some more depth to Wikipedia's coverage of these? Be sure to visit the Wikipedia talk:WikiProject Unrecognized countries, and if you are interested, you can become a Wikipedia:WikiProject Unrecognized countries#Participants. User:Ambivalenthysteria 12:36, 19 Jul 2004 (UTC) * This is indeed interesting. I have added two little countries: Sealand and Principality of Minerva, I think they fit the unrecognized countries-category. I am general interested in small (island) nations, and the Comoros have my special interest. Also added: Taiwan User:Pascal 16:15, 23 Jul 2004 (UTC) Hey, thanks for that link. It's the best resource on some of the more obscure ones (such as Anjouan) that I've seen so far. It can be a bit painful to work out which ones actually ''got'' some functional independence, and which were just optimistic rebel movements, though. User:Ambi 09:02, 7 Aug 2004 (UTC) : You're welcome. I found it also quite interesting, althought Anjouan is really not as obscure as some of the others. Agreed, we have to select the proper ones. (tip: check out the maps on this site http://www.buckyogi.com/footnotes/index.htm). User:Pascal 09:26, 7 Aug 2004 (UTC) ::That's pretty handy too. Shame they only have maps of the Americas though. I wish the notes themselves had more dates, too. User:Ambi 09:34, 7 Aug 2004 (UTC) == English == Hi. Please Wikipedia:Disambiguation ''English'' on your user page. For example, English language. User:RedWolf 02:44, Sep 3, 2004 (UTC) :Done User:Pascal 23:00, 11 Oct 2004 (UTC) ==Comoros maps== I noticed you provided a most excellent map to the article Anjouan. I was wondering if you could perhaps do the same (if you have the source for it) for the other islands of Comoros. The map really makes the article work and it would be an invaluable contribution to the other articles. Thanks for your contributions. User:Arminius 21:29, 24 Oct 2004 (UTC) ==Unverified images== Hi! Thanks for uploading the following images: *:Image:Isla_mas_Afuera_Juan_Fernandez_(Chile).jpg *:Image:Isla_mas_Atierra_Juan_Fernandez_(Chile).jpg *:Image:Isle_of_Youth_(Cuba).jpg *:Image:Dualgauche.jpg I notice it currently doesn't have an Wikipedia:Image copyright tags. Could you add one to let us know its copyright status? (You can use if you release it under the GNU Free Documentation License, if you claim Wikipedia:Fair use, etc.) If you don't know what any of this means, just ''let me know User talk:Poccil'' where you got the images and I'll tag them for you. Thanks so much. User:Poccil_(User_Talk:Poccil,_User:Poccil/Automation.js)">User:Poccil|User:Poccil (User Talk:Poccil, User:Poccil/Automation.js) 22:24, Dec 10, 2004 (UTC) P.S. You can help tag other images at User:Yann/Untagged_Images. Thanks again. == Article Licensing == Hi, I've User:rambot#Free the Rambot Articles project to get users to Wikipedia:Multi-licensing all of their contributions that they've made to either (1) all U.S. state, county, and city articles or (2) all articles, using the Creative Commons Attribution-Share Alike (''CC-by-sa'') v1.0 and v2.0 Creative Commons Licenses or into the public domain if they prefer. The ''CC-by-sa'' license is a true free documentation license that is similar to Wikipedia's license, the GFDL, but it allows other projects, such as WikiTravel, to use our articles. Since you are among the Wikipedia:List_of_Wikipedians_by_number_of_edits Wikipedians by edits, I was wondering if you would be willing to multi-license all of your contributions or at ''minimum'' those on the geographic articles. Over 90% of people asked have agreed. For More Information: *User talk:Ram-Man#Multi-Licensing FAQ - Lots of questions answered *Wikipedia:Multi-licensing *User:rambot#Free the Rambot Articles project To allow us to track those users who muli-license their contributions, many users copy and paste the "" template into their user page, but there are other options at Wikipedia:Template messages/User namespace#Licensing Templates. The following examples could also copied and pasted into your user page: :Option 1 :I agree to Wikipedia:Multi-licensing all my contributions, with the exception of my user pages, as described below: : OR :Option 2 :I agree to Wikipedia:Multi-licensing all my contributions to any U.S. state, county, or city article as described below: : Or if you wanted to place your work into the public domain, you could replace "" with "". If you only prefer using the GFDL, I would like to know that too. ''Please let me know'' what you think at my User talk:Ram-Man. It's important to know either way so no one keeps asking. -- User:Ram-Man ([http://en.wikipedia.org/w/wiki.phtml?title=User_talk:Ram-Man&action=edit§ion=new comment]| User talk:Ram-Man : This copyright issue is way off my interests. It is far to complicated (multi-license version 1 or version 2???, I don't want to get involved in things like this.). GFDL is fine for me, I think - I have added this to my page. I believe it is impossible to find out the exact copyright situation of a certain page when there are more then a dozen possible copyright situations for every user who made an edit. User:Pascal 00:16, 9 Jan 2005 (UTC) == Copyright tag == This is concerning the following images: *:Image:Palau and oceania.jpg *:Image:Palmyra atoll 1970.jpg. As part of the Wikipedia:Untagged Images project, I have tagged it as Wikipedia:Possibly unfree images because I could not determine its copyright status. It seems likely that it is in the public domain but I didn't have enough information to tag it that way. You can help this project by applying Wikipedia:Image copyright tags to all of your uploaded images. Thank you, User:EdwinstearnsEdwinstearns | User talk:Edwinstearns 18:59, 14 Dec 2004 (UTC) Likewise: *:Image:Kasparov-topalov.jpg : Unfortunately, I don't have time to copyright stamp all images I have uploaded. I have however only uploaded maps that are according to my best knowledge not copyrighted. I have not used maps that were marked as copyrighted. Regarding the maps, on the University of Texas map site it is stated: "Most of the maps scanned by the University of Texas Libraries and served from this web site are in the public domain. No permissions are needed to copy them. You may download them and use them as you wish. ''A few maps are copyrighted, and are clearly marked as such.'' Any that are copyrighted by The University of Texas are subject to our Materials Usage Guidelines. A few maps include the official seal of a U.S. Government agency.

We do appreciate hearing from you about your uses of these materials and we would also appreciate your giving this site credit when it is referred to in anything you publish. Other sites may link to our site or to individual maps without our permission." I have added a copyright tag to :Image:Kasparov-topalov.jpg. User:Pascal 23:46, 8 Jan 2005 (UTC) == Cantons of Switserland == Greetings. I see you uploaded :Image:Cantons of Switserland.jpg from [http://www.lib.utexas.edu/maps/europe/switzerland_admin_2000.jpg], and added abbreviations. Unfortunately, I'm not sure if the original image is in the public domain or not. Because of this, I'm adding the image to Wikipedia:Image recreation requests. If you know anything more about the copyright status of the image, or if you'd like to help make a replacement image, let us know! – User:Quadell (User_talk:Quadell) (Wikipedia:Image sleuthing) 15:43, Feb 2, 2005 (UTC)

==About me and my interests== I'm from The Netherlands. My main languages are Dutch, English_Language and German, secondary French, which I can speak and read a bit, and in third place Spanish and Esperanto, which I can read a bit. On wikipedia, I almost exclusively write in English. My interests are first and foremost Chess, but I use Wikipedia mostly to find historical and geographical information. Other interests are Esperanto, geography (especially islands, Micronations, small nations and capitals), space exploration, music, programming, Chesstraining, and other things. Some of my 'own' featured articles I worked on: * Rómulo Betancourt * Federated States of Micronesia, Nan Madol * Comoros, Bob_Denard, Coelacanth * Zanzibar, Pemba, Mafia_Island * 1986 Berlin discotheque bombing * Bruno Hauptmann * Fédération Internationale des Échecs ==License== ==Some links for quick access== *Wikipedia:Public_domain_image_resources *http://www.lib.utexas.edu/maps/index.html == Special char stash == À Á Â Ã Ä Å Æ Ç È É Ê Ë Ì Í Î Ï Ñ Ò Ó Ô Õ Ö Ø Ù Ú Û Ü ß à á â ã ä å æ ç è é ê ë ì í î ï ñ ò ó ô õ ö ø ù ú û ü ÿ

==Carbon nanotubes== From the table of pressures and examples of those pressures: "100 GPa - Carbon nanotubes (CNTs)" - what about carbon nanotubes at 100 GPa? Is that the pressure at which they break under force in a particular direction? -- User:Ke4roh 13:14, 21 Jan 2004 (UTC) : Added link for tensile strength, to clarify that 100 GPa is not a pressure here. User:Markus Kuhn 11:06, 30 Apr 2005 (UTC) ==Mars atmospheric pressure== This artical says it is 1 kPa. The mars article says it is 0.1 kPa. One of these is wrong. My understanding is that it is 0.7-0.9 kPa which is just slightly above the point where water cannot exist in the liquid phase. Can those who made the wrong example make a correction? -- Terrell Larson : The Mars article (and other sources I checked) say it is typically 0.75 kPa. The 1 kPa order-of-magnitude figure that is given here seems to be a crude, but easy to memorize, valid, rounded version of that. User:Markus Kuhn 11:06, 30 Apr 2005 (UTC)
