ok I've figured out how would it look like in "my style solution" but I still have some questions. Why does the $$ u\frac{dn}{dt} $$ term disappears? when i rewrote it using mass instead of moles, the term $$\frac{dm}{dt}CvT$$ seems to have a non zero value (there is a mass flowing out, that...

Hi there again. I have a second problem for which I don't have an answer to compare with, hence I'm kindly asking someone to check the solution of mine. lower case w and q are the work and heat per 1kg respectively, and w's with a vector are of course the velocities at the inlet and at the outlet.

Thank You a lot, I've tried also this way but with no results. But to be sure, what for does the "n" stands for in your first equation?

Hi there. I have a problem solving above problem. How can I move on with my solution? It seems to me that I have proper approach but I'm just stuck with the energy equation ;/ Part of solution below:
