← ScienceWhich outcome results when a Carnot engine operates with irreversible heat transfer across a finite temperature difference?
A)Reduced engine efficiency approaching ideal
B)Increased heat input at constant temperature
C)Entropy generation decreasing cycle area✓
D)Temperature and pressure equilibrium increase cycle area
💡 Explanation
When heat transfer occurs across a finite temperature difference, irreversibility introduces entropy generation because the process is never in equilibrium, reducing the area within the T-S diagram. Therefore entropy generation increases, rather than ideal efficiency, constant temperature or increased area which violate thermodynamic principals.
