[edit]I think there is an error in the equation because Position 1 (input) does not appear in it. Biscuittin (talk) 16:44, 17 May 2011 (UTC)
- The equation, as shown in the article, would always give a zero result. Biscuittin (talk) 20:30, 17 May 2011 (UTC)
The text mentions Eq 1.10 but starts with equation 1.13.
Eq 1.13 has the term M_r, while the text has the term M_T. Are these intended to be the same. Explicit definitions of the terms in the equations would be helpful - either in the text or in a table. — Preceding unsigned comment added by 4.71.4.18 (talk) 13:52, 7 March 2013 (UTC)
This article is very unclear. — Preceding unsigned comment added by 68.100.44.52 (talk) 02:45, 10 April 2013 (UTC)
"unclear" seems like an under-statement. This page looks like its been cut&pasted from a book, removing all context. — Preceding unsigned comment added by 174.117.121.41 (talk) 00:21, 13 April 2013 (UTC)
The article needs to be completely rewritten. — Preceding unsigned comment added by Súl iolar d'aois (talk • contribs) 15:47, 29 April 2014 (UTC)
Let's try to be more specific, in the hope that it might precipitate some change. This article is lacking in the following important ways, I think: it does not provide much in terms of context, does not define many of the variables that are used in the equations (assuming some standard notation, probably), does not show some of the equations it references, gives no examples of applications of these equations and principles, and gives little to no conceptual discussion of what follows from the equations shown, instead repeating that the equation is important in various areas. This could be a very useful page, I believe, if those issues were mitigated. — Preceding unsigned comment added by 107.19.189.206 (talk) 05:04, 13 November 2015 (UTC)
This equation looks like a maze game
[edit]Let's look at (3)
the presence of 6 velocity vector makes it look like a bunch of hair, don't know where to probe?
isn't it a maze game guys!
I introduced a new equation (not yet recognized) at centrifugal pump article (talk)

I have the cited book and might one day try and fix some stuff here. But meanwhile thanks to the links in File:Euler-turbinaegyenlethez.svg both [1] and [2] provide better starting points if one understands Hungarian or Norwegian... --Zommuter (talk) 07:21, 1 April 2021 (UTC)
