Minor Correction: 4:40 The schematic of a turbine should show the gas expanding, not compressing (right side should be larger than left side).

I very much appreciate how much information you pack into these short episodes. I have referenced your videos in several of my design projects and you genuinely help me understand relationships that are not emphasized in traditional textbook form. Thanks for what you do!

I will try to follow the whole thermodynamics playlist and hopefully I will finally pass this subject next year! My issue is I quickly lose oversight and dont practice nearly enough.

Your videos are awesome, I was scared when I saw that you were not uploading anymore. I am very happy to see you again :)

You drew the argon turbine as a compressor (5 min mark), great job on all these btw!!

Fantastic! Please say what is the App you use for your videos. Samsung Notes?

What is difference between isoentropic efficiency and thermal efficiency..

[juohan]

Isentropic compression is the ideal process that requires least amount of work input. But why isothermal and polytropic compression has lower work between same pressure limits?
