The animation of the throttling valve at the beginning is really helpful. Thank you for the video.

[@QuestionSolutions]

You're very welcome! Best wishes with your studies.

I don't know how to express. Even though we were only exposed to this knowledge for the first time, my professor did not explain it carefully for us. Thank you so much for the video.

[@QuestionSolutions]

Glad I could help and you're very welcome!

[@shafqatalibhutto9597]

Your Teaching way is brilliant so keep it up & add more subject in yr playlist like thi ❤❤

[@QuestionSolutions]

Thank you very much ❤

çok faydalıydı teşekkürler
ı get it clearly thank you so much

[@QuestionSolutions]

You're very welcome!

[@panoskol3816]

Incredible explanation. Thank you.

[@QuestionSolutions]

Thank you very much!

[@shafqatalibhutto9597]

Bro kindly make more video on other engineering subjects of Mechanical thank you yr video is really helpful 💕

[@QuestionSolutions]

I will, it's definitely on my list to do.

Professor I have a question,I wonder why enthalpy combines internal energy and flovwork?Could you explain me briefly

[@QuestionSolutions]

Your textbook should have a really good section about enthalpy. Were you able to read it? This website ( www.sciencedirect.com/topics/biochemistry-genetics-and-molecular-biology/enthalpy#:~:text=Enthalpy%2C%20normally%20denoted%20H%2C%20is,H%20%3D%20%CE%94%20U%20%2B%20%CE%94%20pV ) also goes into enthalpy, how it's related to internal energy plus pressure and volume (which is related to flow work). If you have sometime, please read it to get a better understanding.

In all these cases both pressure and temperature drop, and enthalpy is a combined measure pf pressure and internal energy. How could they possibly be equal at the inlet and outlet? What don't I understand about the concept of enthalpy?

Please see: www.physicsforums.com/threads/the-principle-behind-throttling-valves.67757/#:~:text=In%20summary%2C%20throttling%20valves%20are,it%20passes%20through%20the%20valve.
There is a good discussion going on about this that might shed some insight to your problem as well.
If you want to go really deep, you can read this as well: www.sciencedirect.com/topics/engineering/throttling-process
In real life, there are some changes to pressure and temperature, but it is negligible in the "grand scheme" of things when we write an energy balance equation because of the factors we consider when writing the said equation. So enthalpy remains relatively equal to each other at the inlet and outlet.
