The cooling you are talking about is an isochoric process (a vertical line on the PV diagram, going up). You failed to mention this. Then what? How do you bring back your fluid to its initial state to repeat the cycle? Or do you just discard the heated fluid and replace it with a new one? But...

You will have to use clearer language to make sure everyone follows. For example: You specified in the OP that the process is adiabatic in the first scenario; therefore, there is no heat exchange, no cooling. If by "cooling" you mean "a lower temperature of the fluid", then I don't understand...

These reflections just reinforce my belief that criminal laws shouldn't exist. I think a strong Civil Court system would work just as well and, without being perfect, be fairer. It's more fundamental than just AI-related cases.

All energy in the second scenario can be recovered as well. It is only wasted if you don't recuperate it somehow. (To heat something, for example.) There you go. Well, if you don't need to heat something and you don't need to rotate a turbine, why would anyone spend the energy in the first...

From the OP: If I understand correctly, you seem to claim that both scenarios give the same amount of cooling for different work inputs. But in the first scenario, there is no heat loss, and in the second one, there is a massive heat loss. This energy can be used for something else; it had to...

Ford has played with the idea as far back as 1936:

The heat loss in an isobaric cooling process is not equal to the work done on the ideal gas. Instead, the heat transferred (##Q##) is related to the change in internal energy (##U##) and the work done (##W##) by the equation ##Q = \Delta U + W##, where the work done is associated with the...

That is also an isobaric compression, requiring more work. Do you mean like an isothermal expansion? Where both work is released and heat added? Well, I'm glad it is, then it will be easy for you to do the work and show it to us. Just use the LaTeX notation to ease the reading of your...

It is not clear which processes (isochoric, isobaric, isentropic, isothermal) you are using to cool and depressurize the fluid in the second scenario. One could assume an isochoric cooling followed by an isothermal expansion, but you seem to talk about opening a valve between the cylinder and...

So, apparently, Remember Monday is the latest sensation on TikTok with Fat Bottomed Girls.

We kind of figured that out from your signature: I met a young man in his twenties a few years ago who had difficulties understanding how the radio in his car works. When I told him that I used to have an AM radio in my first cars, he had absolutely no clue what I was talking about. (Telling...

Of course. Use LibreOffice, which is available for Windows, Mac, and Linux, so you can even try it before installing Linux. https://en.libre-office.fr/article.php/working-with-microsoft-file-formats-in-libreoffice-a-comprehensive-guide https://en.wikipedia.org/wiki/LibreOffice...

If you want the NVR at home (you were mentioning off-site in the OP), it seems you need ONVIF-compliant products. For example:

All of these cameras usually offer some cloud storage you can access with their app, for a fee. For example, Tapo offers Tapo Care for 34.99 $/year:
