Thermodynamic cycles: nature of Stirling and Ericsson cycles Classify the Stirling and Ericsson cycles by reversibility and idealization. Choose the correct option.

Difficulty: Easy

reversible cycles
irreversible cycles
semi-reversible cycles
quasi-static cycles

Correct Answer: reversible cycles

Explanation:

Concept
Ideal Stirling and Ericsson cycles are composed of isothermal and isochoric/isobaric processes with perfect regeneration. In the idealized sense, they are reversible cycles, achieving Carnot efficiency between the same temperature limits.

Final Answer
reversible cycles
