Well, thanks, but I've been editing occasionally for nearly 3 years now, so I'm a mite confused why I'm getting a welcome message now. Mermaldad (talk) 02:05, 2 June 2012 (UTC)[reply]
Hello Mermaldad. On 11 December you edited our articles on Stagnation pressure and Total pressure. Thank you for taking an interest in these two articles. Your edits implied that stagnation pressure and total pressure are synonymous – that either term can be used as an alternative for the other. I have reverted your edits – see my diff1 and diff2. I did so for the following reasons.
In our article on stagnation pressure, the relevant source is L.J. Clancy’s Aerodynamics, section 3.5. (Section 3.12 is also cited as a source.) Clancy presents total pressure and stagnation pressure as two distinct concepts. He does not suggest they are synonymous. Your edit to the article on stagnation pressure was therefore inconsistent with the cited source. Some authors of introductory textbooks on fluid mechanics omit the concept of total pressure in the interests of simplicity, or they present stagnation and total pressure as synonymous, again in the interests of simplicity. Clancy is not one of those authors.
Clancy explains that total pressure is defined for every point in a flow field but stagnation pressure is only defined at stagnation points. Various physical laws, including Bernoulli’s theorem, state correctly that at stagnation points in incompressible flows, stagnation pressure and total pressure are numerically equal. However, that does not mean the two are synonymous. The same consideration can be seen in Newton’s 2nd law of motion which states that the resultant force acting on a body is numerically equal to the mass of the body multiplied by the body’s acceleration; but that does not mean "mass times acceleration" is an alternate description of the expression "resultant force acting on a body".
Please keep up the good work! Dolphin (t) 11:12, 13 December 2014 (UTC)[reply]

SwisterTwister talk 05:04, 21 August 2016 (UTC)[reply]Hi Mermaldad,
It's only been a bit over two years since you asked for a picture of a ball transfer unit, and now there is one! Amazing how quickly Wikipedians can react ;-] --Slashme (talk) 05:16, 31 December 2016 (UTC)[reply]
Thanks, Slashme!
Yeah, sometimes other things, like our lives, get in the way of a speedy response. And sometimes it's just comedic timing. ;-) Mermaldad (talk) 00:58, 17 November 2019 (UTC)[reply]
Hi. Thank you for your recent edits. An automated process has detected that when you recently edited List of rivers of California, you added links pointing to the disambiguation pages Willow Creek and Cox Creek. Such links are usually incorrect, since a disambiguation page is merely a list of unrelated topics with similar titles. (Read the FAQ • Join us at the DPL WikiProject.)

Thanks for your contributions to Hacker Public Radio. Unfortunately, it is not ready for publishing because it needs more sources to establish notability. Your article is now a draft where you can improve it undisturbed for a while.
Please see more information at Help:Unreviewed new page. When the article is ready for publication, please click on the "Submit your draft for review!" button at the top of the page. EggRoll97 (talk) 03:09, 5 October 2023 (UTC)[reply]
Hello, Mermaldad. It has been over six months since you last edited the Articles for Creation submission or Draft page you started, "Hacker Public Radio".
In accordance with our policy that Wikipedia is not for the indefinite hosting of material, the draft has been deleted. When you plan on working on it further and you wish to retrieve it, you can request its undeletion. An administrator will, in most cases, restore the submission so you can continue to work on it.
Thanks for your submission to Wikipedia, and happy editing. ✗plicit 14:04, 22 April 2024 (UTC)[reply]
