如何计算Carnot Efficiency
learn.whatIsHeading
Carnot efficiency is the theoretical maximum efficiency of a heat engine operating between two temperature reservoirs. No real engine can exceed this limit.
公式
The calculator applies η = 1 - (T_cold / T_hot)
分步指南
- 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
例题解析
输入
T_hot = 600 K, T_cold = 300 K
结果
η_max = 50%
Best possible performance
常见错误注意事项
- ✕Using Celsius instead of Kelvin temperatures
- ✕Assuming actual engines approach Carnot efficiency
常见问题
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.
