In a Carnot cycle, a system or engine transfers energy in the form of heat between two thermal reservoirs at temperatures and (referred to as the hot and cold reservoirs, respectively), and a part of this transferred energy is converted to the work done by the system.
In order to obtain a continuous supply of work, the working substance is subjected to a cycle of quasi-static operations known as the Carnot cycle. The cycle, when it acts as a heat engine, consists of various steps, which are as follows.
: an ideal reversible closed thermodynamic cycle in which the working substance goes through the four successive operations of isothermal expansion to a desired point, adiabatic expansion to a desired point, isothermal compression, and adiabatic compression back to its initial state.
Describe the Carnot cycle with the roles of all four processes involved; Outline the Carnot principle and its implications; Demonstrate the equivalence of the Carnot principle and the second law of thermodynamics
What is Carnot Cycle? A Carnot cycle is a closed thermodynamic cycle that is ideal and reversible. Isothermal expansion, adiabatic expansion, isothermal compression, and adiabatic compression are the four successive processes that take place.
The book proposed a generalized theory of heat engines, as well as an idealized model of a thermodynamic system for a heat engine that is now known as the Carnot cycle. Carnot developed the foundation of the second law of thermodynamics, and is often described as the "Father of thermodynamics."
Carnot cycle, in heat engines, ideal cyclical sequence of changes of pressures and temperatures of a fluid, such as a gas used in an engine, conceived early in the 19th century by the French engineer Sadi Carnot.
