What is the reason behind choosing adiabatic and isothermal process for carnot engine? My book states the following reason. I am not able to understand it. It would be great if you could put it in

Carnot's theorem, developed in 1824 by Nicolas Léonard Sadi Carnot, also called Carnot's rule, is a principle that specifies limits on the maximum efficiency any heat engine can obtain. The efficiency of a Carnot engine depends solely on the temperatures of the hot and cold reservoirs. And we know from the 1 st law of thermodynamics, work is done by the heat engine, W=Q H +Q L. Here Q H >0 and Q L <0. The Carnot cycle in this heat engine consists of two isentropic and two isothermal processes.

The four reversible processes that make up the Carnot cycle are as follows: Reversible Isothermal Expansion (process 1-2): JIF 314 Thermodynamics Chapter 7 The Carnot Cycle and thermodynamic temperature scale Learn the concepts of Class 11 Physics Thermodynamics with Videos and Stories. Define what is carnot engine, explain carnot cycle, establish carnot theorem, prove carnot cycle is universal. Realise that Carnot Cycle is not a practical possibility. 2020-02-12 · There are several ways to phrase the second law of thermodynamics, but basically it places a limitation on how efficient any transfer of heat can be. According to the second law of thermodynamics, some heat will always be lost in the process, which is why it is not possible to have a completely reversible process in the real world.

Isothermal Expansion ; Adiabatic or Isentropic Expansion ; Isothermal Compression ; Isentropic Compression ; Process 1-2 Isothermal Expansion. The source (hot body, H.B) at a higher temperature is brought in contact with the bottom B of the cylinder. The air expands, practically at constant temperature T1, from v1 to v2.

To understand the operation involved in the Carnot engine we talk about the processes involved in the Carnot cycle. Carnot cycle is based on reversibility or it is a reversible cycle.

So in representing Sadi Carnot’s cycle of 1824 with both p, v and T,s diagrams (which he was unable to do) almost a century of associated thermodynamics history is involved.

In a Carnot cycle, the system executing the cycle undergoes a series of four internally reversible processes: two isentropic processes (reversible adiabatic) alternated with two isothermal processes: isentropic compression – The gas is compressed adiabatically from state 1 to state 2, where the temperature is T H .
