Which outcome occurs when an ideal closed Brayton cycle operates far from equilibrium?

A)Increased isentropic efficiency degradation occurs
B)Compression ratios reach theoretical limits
C)Internal irreversibilities severely decrease output
D)Net cycle work approaches maximum value

💡 Explanation

Output declines when the Brayton cycle operates irreversibly because internal irreversibilities reduce efficiency. Specifically entropy generation via friction dominates, therefore less work is extracted, rather than achieving ideal efficiency.
