In order to calculate the Carnot efficiency, we can use the formula below:
[tex]e=1-\frac{T_c}{T_h}[/tex]Where Tc and Th are the cold (low) and heat (high) temperature (in Kelvin).
So, using the given information, we have:
[tex]e=1-\frac{182}{343.6}=1-0.5297=0.4703=47.03\%[/tex]Therefore the Carnot efficiency is 47.03%.
