Talk about Pioneers in the Development of Centrifugal Pump section (C.P. Article)

Hello, I see it’s so rich content but the restricted matching of the topics with the scope of C.P article because it is single in convert mechanics energy to fluid dynamics energy of an incompressible liquid not engage with thermodynamic and compressible fluid. May be some other source will adapt in this section.

Sincerely,

Thank you about your idea. of course all of hydrodynamic explanation is based on the assumption like that.

Hello, I'm Oshwah. I noticed that you recently removed some content from Centrifugal pump  with this edit, without adequately explaining why. In the future, it would be helpful to others if you described your changes to Wikipedia with an edit summary. If this was a mistake, don't worry, the removed content has been restored. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. ~Oshwah~^{(talk) (contribs)} 03:08, 9 June 2016 (UTC)

Please do not remove content or templates from pages on Wikipedia, as you did to Centrifugal pump with this edit, without giving a valid reason for the removal in the edit summary. Your content removal does not appear constructive and has been reverted. Please make use of the sandbox if you'd like to experiment with test edits. Thank you.  I dream of horses  If you reply here, please ping me by adding {{U|I dream of horses}} to your message  (talk to me) (My edits) @ 03:33, 9 June 2016 (UTC)

Reverted your contributions at Talk:Centrifugal pump

You made quite a hash of that talk page with deletions, random signature insertions, and personal theories. So I reverted all that. Please start a new section at the end of the talk page and leave a concise comment if you have ideas for improving the article. This is not a good place to make technical arguments, but if you've got your results published, please do reference that. Dicklyon (talk) 04:08, 22 March 2020 (UTC)

I reverted again. Please just start a new section at the end of the talk page and make a more concise proposal of how you would like to see the article improved, instead of sprinkling odd changes throughout the talk page. Dicklyon (talk) 06:00, 29 March 2020 (UTC)
