← ScienceWhich risk increases when a Carnot engine design uses irreversible heat exchangers?
A)Lower overall thermodynamic efficiency✓
B)Increased engine power output
C)Higher theoretical Carnot efficiency
D)Decreased system irreversibility
💡 Explanation
Lower efficiency results because using irreversible heat exchangers introduces entropy generation that reduces Carnot efficiency. The second law imposes an upper limit, therefore the actual process deviates more, rather than improving ideal outputs.
