Hello, fellow veterans, today I will share with you Bicano and a brief introduction to related knowledge of Carnot\’s theorem. I hope it will be helpful to everyone. If it can help you, please pay attention to this site and bookmark it. Your support is our biggest motivation. Thank you everyone. Let’s get started!

1. How to calculate the net work of the Carnot heat engine
1. The efficiency of the cycle is equal to the ratio of the net work done by the system to the heat absorbed by the entire cycle process .
2. In the first isothermal expansion, the system does positive work to the outside world. In the second adiabatic expansion, the system also does positive work to the outside world, but in the following During isothermal and adiabatic processes, the system does negative work on the outside world.
3. When calculating efficiency, the algebraic sum of positive and negative work should be used (i.e. net work) divided by absorbed heat
2. Brief description of Carnot\’s theorem
Carnot\’s theorem is a theorem proposed by Carnot in 1824 based on the Carnot cycle. It states that the efficiency of all reversible heat engines working between the same high-temperature heat source and the same low-temperature heat source is equal. Regardless of the working substance; the efficiency of any irreversible heat engine that works between the same high-temperature heat source and the same low-temperature heat source cannot be greater than that of a reversible heat engine.
OK, this article ends here, I hope it will be helpful to everyone.
