The maximum theoretical thermal efficiency of a steam engine that is supplied steam at a temperature of 600ºC and exhausts it at a temperature of 200ºC is

Question

Quizplus · Accepted Answer

The maximum theoretical thermal efficiency of a steam engine can be calculated using the Carnot efficiency formula: $\eta = 1 - \frac{T_c}{T_h}$, where $\eta$ is the efficiency, $T_c$ is the cold reservoir temperature, and $T_h$ is the hot reservoir temperature, with temperatures in Kelvin. Converting the given temperatures to Kelvin: 600ºC = 873K and 200ºC = 473K. Thus, $\eta = 1 - \frac{473}{873} = 0.458$ or 45.8%.
