Carnot heat engine
Follow two isotherms and two adiabats around a reversible cycle.
What to notice
Efficiency depends on the absolute hot and cold temperatures. The enclosed area is work per cycle.
Key relation
η = 1 − Tc/Th
Try this
Raise the hot-reservoir temperature and compare efficiency.
What you can change
- Hot reservoir: 450 to 800 K
- Cold reservoir: 250 to 400 K
- Isothermal expansion ratio: 2 to 5 ×
