Clausius Inequality (Cont’d)<br />
Therefore, the work W c which could not be a<br />
positive quantity in the regular case, cannot be<br />
a negative quantity in the reversed case.<br />
Then it follows that W C int rev =0 since it cannot be<br />
positive or negative quantity and therefore<br />
<br />
Q<br />
<br />
<br />
T <br />
intrev<br />
Thus we conclude that the equality in the<br />
Clausius inequality holds for totally or just<br />
internally reversible cycles and the inequality<br />
for the irreversible ones.<br />
