← ScienceWhich consequence arises when a two-stage Carnot engine’s intermediate temperature is incorrectly estimated?
A)Increased compression energy consumption
B)Reduced overall thermal efficiency✓
C)Elevated cycle irreversibility losses
D)Unchanged heat transfer characteristics
💡 Explanation
Reduced thermal efficiency results because inaccurately estimating the intermediate temperature prevents optimal heat transfer and work extraction at each stage, hindering maximum conversion based on the Carnot principle; therefore, the overall efficiency drops, rather than alternatives like preserving transfer characteristics.
