Entropy - Thermodynamics

[@md.rahmatullahrafi5417]

great video,,,,thanks a lot

Is it possible for you to upload videos also for the topic of exergy? Your videos are the best!

[@WannabeProfessor86]

I will try. I am very bad at this KZbin thing haha.

@@WannabeProfessor86I don't think so, I recommended your channel to many friends of mine:)

Hello, Prof! I wanted a clarification, is the entropy of an irreversible H.E. lesser than zero or greater than zero? Hope this will be answered. Because in our discussion the entropy of an irrev is greater than zero and always positive.

[@WannabeProfessor86]

That's a great question. The entropy generation of every irreversible process is always positive. As a matter of fact every real process has a positive change of entropy (change entropy is different than entropy generation) unless the process has negative heat transfer. Taking heat out of a system is the only way to reduce the entropy of that system. Hope this helps.

Excellent video. But we need lectures on gas power cycles.

[@WannabeProfessor86]

Thank you. Hopefully I can upload something soon.

[@rayhangu8403]

How about otto cycle? Is that needed?

[@WannabeProfessor86]

I'll try to upload a video on the cycles too.

gg lecture. this is my secret success tips now:)

Glad I could help.
