[QUOTE="Kolin101, post: 6634698, member: 701588"] 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 caries out internal energy at T=300K) and unfortunately Cv is not known either ;/ (new solution attached below the quote) [ATTACH type="full" alt="tank discharge.jpg"]301808[/ATTACH] [/QUOTE]
