i just wanted to leave a comment here to say that this professor is the best thing i ever came across. He managed to teach me all the things i needed to pass thermodynamics and understand what i was doing. I tought thermodynamics was super hard to learn but i realized it was just my useless professor with zero skill to teach.
I don't know if you are still waiting for an answer or no . my professor said we call it COP because it's usually more than one and efficiency can't be more than one , is it always more than one I'm not sure but I believe so
you can prove COP(hp) = COP(ref) + 1 by applying first law and dividing whole equation by W(in) . So that means COP(ref) could be less than 1 but COP(hp) is always greater than 1

Thanks Mr.David Miller , videos are really helpful
Awesome video sir! Thank you!

Yeah... first like... Waiting for next lectures
Patience, patience. It takes a while to timestamp the lectures.
Is there any way that we can get the solutions to those homework assignments?
please if anyone have the notes of this lectures please send it
