Darcy–Weisbach equation
I see that no one has replied to your post at the Help desk, so I had a look at your contributions in the Darcy–Weisbach equation article. I know nothing of fluid dynamics so cannot comment on whether your material was correct physics. But you should take a look at the Wikipedia policy page No original research; Wikipedia articles should only contain material that has already been published in reliable sources such as books, journals, news outlets and such like. For a brief guide to formatting, try the Cheatsheet. Formatting mathematics is tricky; the help page is Help:Displaying a formula. -- John of Reading (talk) 07:19, 7 September 2011 (UTC)
