Is Carnot efficiency the same as thermal efficiency?
Carnot efficiency is the theoretical maximum efficiency that a heat engine can achieve, while thermal efficiency is the actual efficiency of a real-world heat engine. Carnot efficiency does not take into account any losses or inefficiencies, while thermal efficiency reflects the true efficiency of a system.
Carnot efficiency is calculated using the formula (Th - Tc) / Th, where Th is the temperature of the hot reservoir and Tc is the temperature of the cold reservoir. This formula represents the maximum possible efficiency of a heat engine operating between these two temperatures.
Thermal efficiency is affected by several factors, including the design and construction of the heat engine, the temperature difference between the hot and cold reservoirs, and any losses due to friction or heat transfer. The type of fuel and the combustion process also play a role in determining thermal efficiency.
Carnot efficiency is considered an ideal because it represents the maximum possible efficiency that can be achieved by a heat engine operating between two temperatures. It is based on the laws of thermodynamics and assumes no losses or inefficiencies, making it a theoretical benchmark for evaluating the performance of real-world systems.
No, thermal efficiency can never be higher than Carnot efficiency. This is because Carnot efficiency represents the maximum possible efficiency and takes into account all the losses and inefficiencies that occur in real-world systems. In order to achieve Carnot efficiency, a heat engine would have to operate at 100% efficiency, which is impossible due to the laws of thermodynamics.
