Carnot efficiency is the theoretical maximum efficiency of a heat engine operating between two temperature reservoirs. No real engine can exceed this limit.
Công thức
The calculator applies η = 1 - (T_cold / T_hot)
Hướng dẫn từng bước
- 1Enter hot reservoir temperature (T_hot) and cold reservoir temperature (T_cold)
- 2The calculator applies η = 1 - (T_cold / T_hot)
- 3Results show maximum theoretical efficiency
Ví dụ có lời giải
đầu vào
T_hot = 600 K, T_cold = 300 K
Kết quả
η_max = 50%
Best possible performance
Lỗi thường gặp cần tránh
- ✕Using Celsius instead of Kelvin temperatures
- ✕Assuming actual engines approach Carnot efficiency
Câu hỏi thường gặp
Why can't we achieve Carnot efficiency in real engines?
Real engines have friction, heat losses, and irreversible processes that reduce efficiency below the theoretical maximum.
Does Carnot efficiency depend on the working fluid?
No, Carnot efficiency depends only on the two reservoir temperatures, not on the engine type or working substance.
