April 2014

Hello, I'm BracketBot. I have automatically detected that your edit to Process duct work may have broken the syntax by modifying 1 "()"s and 1 "[]"s. If you have, don't worry: just edit the page again to fix it. If I misunderstood what happened, or if you have any questions, you can leave a message on my operator's talk page.

List of unpaired brackets remaining on the page:

are lower than the allowable stresses for straight duct by a K factor = 1.65/(h 2/3power) where [h = t (duct) * R (elbow) /(r(duct)*r (duct). This equation, or similar equations is found in Tubular Steel Structures section

It's OK to remove this message. Also, to stop receiving these messages, follow these opt-out instructions. Thanks, BracketBot (talk) 14:51, 24 April 2014 (UTC)[reply]

Replaceable fair use File:Duct Shipping Spider.jpg

Thanks for uploading File:Duct Shipping Spider.jpg. I noticed that this file is being used under a claim of fair use. However, I think that the way it is being used fails the first non-free content criterion. This criterion states that files used under claims of fair use may have no free equivalent; in other words, if the file could be adequately covered by a freely-licensed file or by text alone, then it may not be used on Wikipedia. If you believe this file is not replaceable, please:

Go to the file description page and add the text {{di-replaceable fair use disputed|<your reason>}} below the original replaceable fair use template, replacing <your reason> with a short explanation of why the file is not replaceable.
On the file discussion page, write a full explanation of why you believe the file is not replaceable.

Alternatively, you can also choose to replace this non-free media item by finding freely licensed media of the same subject, requesting that the copyright holder release this (or similar) media under a free license, or by creating new media yourself (for example, by taking your own photograph of the subject).

If you have uploaded other non-free media, consider checking that you have specified how these media fully satisfy our non-free content criteria. You can find a list of description pages you have edited by clicking on this link. Note that even if you follow steps 1 and 2 above, non-free media which could be replaced by freely licensed alternatives will be deleted 2 days after this notification (7 days if uploaded before 13 July 2006), per the non-free content policy. If you have any questions, please ask them at the Media copyright questions page. Thank you. Fut.Perf. ☼ 14:37, 23 May 2014 (UTC)[reply]

Ductwork PROD

The PROD was removed with no improvement whatsoever. Nothing changed. For eight years this has been a wonderful article, but it's not encyclopedic. It is the original research of what appears to be one individual without as much as a single reference. ~~
