← ScienceWhich inefficiency increases when thermal shock causes cracking in heat exchanger tubes?
A)Increased entropy generation✓
B)Decreased heat capacity
C)Higher convective heat transfer
D)Elevated system resonance
💡 Explanation
Cracking promotes turbulent flow and irreversible mixing, which results in entropy generation in the system. Because this occurs due to increased disorder and energy dissipation, therefore entropy increases, rather than changes in heat capacity or resonance.
