[edit] Heat of compressed gas
The heat of a compressed gas does not come from the inefficiany of the machine compressing the gas. I am not sure why you insist on this error but I am not going to get into an edit war with you Mark. —The preceding unsigned comment was added by Qaz (talk • contribs) 4 March 2004 (UTC).
[edit] Relative efficiencies
Can anyone provide any figures for the relative efficiency of the various designs of compressor? This is information I for one would find extremely useful.--81.179.91.108 23:55, 16 June 2006 (UTC)
- I second the request of the above person. It would seem to me that a piston design would produce much lower efficiencies than a turbine design, but just how much better or worse? I've dug into my thermo books, and can't seem to find anything on excpected mechanical efficiencies. ~ZirbMonkey - 27 June, 2006 read it by Badr AL-Sowayan

- I would suggest that you read the Compressor Handbook, Editor: Paul Hanlon, published by McGraw Hill, January 2001, ISBN 0070260052. - mbeychok 07:49, 28 January 2007 (UTC)
[edit] Hydrogen compressor

[edit] Air quality test
I need help. Carrying out an Air Quality Test of air compressed into an SCBA cylinder. The water value reads 180mg/m3. The cylinder is 9kg in size. The Standard required in the vessel where I work (FPSO is 30mg/m3. How is this possible for God's sake! Give me a clue. The test time is 10 Minutes using Drager kit. The instruction in the water tube is of October 2005. Is there a way of converting mg/m3 to ppm? Pls let me know.

- Read this Wikipedia article: click here ==> Useful conversions and formulas for air dispersion modeling#Converting air pollutant concentrations. It has exactly what you are looking for. - mbeychok 18:25, 19 January 2007 (UTC)
[edit] Reason for changing photograph
I replaced the original photo with a better one of a single-stage centrifugal compressor because I thought the original photo was a rather scruffy looking photo of small portable air compressor. I think the photo that I used is much cleaner and neater, and more representative of the thousands of compressors in industrial use. If anyone has a better one in color, that would be better yet. - mbeychok 08:03, 19 January 2007 (UTC)
[edit] How do Thermal expansion or Decompression relate to Gas compressor ??
I think that some of us get carried away with providing Wiki links. I just read the Thermal expansion article very thoroughly. It is obviously about the thermal expansion of liquids and solids. I fail to see any relation between that article and this article on Gas compressors. The lead-in sentence of this article about gas compressors states: A gas compressor is a mechanical device that increases the pressure of a gas by reducing its volume.
An article about the thermal expansion of liquids or the thermal expansion joints in bridges and railroads has no absolutely no beneficial connection whatsoever with this article. Wiki links in the "See also" section are meant to point the reader to related articles with some real, beneficial connection to gas compressors.
I also feel the same is true of the link to the Decompression article. It has no connection to gas compressors. I think it behooves all of us, myself included, to be more careful about adding unrelated links to the "See also" section of any articles. What do others think about this subject? - mbeychok 00:36, 29 January 2007 (UTC)
