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]

Total and stagnation pressures

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]

Ball transfer unit picture

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]

Disambiguation link notification for November 4

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.)
