A Carnot cycle representes a gas undergoing a theoretical - means it cannot be implemented realistically - thermodynamic cycle composed of 4 reversible steps (meaning you can go back and everything will be back to the state it was, or scientifically speaking, the entropy of the universe will remain constant):
1- isothermal expansion of the gas (working fluid) - heat is added from the surroundings to the working fuild and it expands at constant temperature;
2- isentropic expansion of the gas - the gas is allowed to expand and produce work;
3- isothermal compression of the gas - the gas rejects heat to the surroundings at constant temperature;
4- isentropic compression of the gas - the gas is compressed and work is need for that compression.

Why you learn carnot cycle while it is not use in reality?
because it is the best theoretical engine. our aim is always to make our practical engine as close as that of carnot. if u don't know about the carnot cycle then how will u do that.
Limitations of the Carnot cycle for the operation of the steam power plant?
The Carnot cycle gives the theoretical maximum efficiency of an engine operating between two heat reservoirs. The Carnot cycle is an idealized engine cycle that is thermodynamically reversible. Real systems such as power plants are not reversible, and the entropy of a real material changes with temperature (which is not accounted for by the Carnot cycle). A steam power plant operates closer to a cycle known as the Rankine cycle.
Why efficiency of carnot heat engine is always greater than that of an actual engine?
The efficiency of a Carnot engine is theoretically always greater than that of an actual engine. The fact that it is impossible to build a thermodynamically reversable engine, which is one of the variables necessary to calculate its superiority to a real heat engine, makes the theorum practical for assessing a real heat engines efficiency only.
What are the differene between stirling cycle and carnot cycle?
In Carnot & Stirling cycle there were 2 isothermal processes. but in Stirling engine other 2 processes are constant volume processes whereas in Carnot other 2 processes are isentropic processes. Stirling engine has low maintenance and easy to built because of there construction. Both cycle's efficiencies near to same. but operating according to there applications.
Carnot cycle is practically possible or not?
no, a Carnot cycle is not practiclly possible.bcz carnot consist of two cycles. i.e 1-rev. adiabatic 2-isothermal
What is the carnot statement of the second law of thermodynamics?
The efficiency of a quasi-static or reversible Carnot cycle depends only on the temperatures of the two heat reservoirs, and is the same, whatever the working substance. A Carnot engine operated in this way is the most efficient possible heat engine using those two temperatures
Which is the carnot engine formula?
carnot = carrot
What is reversibility in thermodynamics?
Ideal Carnot Cycle is one example It is a process that does not have an energy loss.
What is the reverse of a carnot engine?
reverse carnot engine is also called a REFRIGERATION SYSTEM.
When was carnot engine develop?
Carnot heat engine was develop in 1824 by Nicolas Leonard.
What is the difference between carnot heat engine and a heat engine?
difference schematic diagram between carnot heat engine and heat engine
What is the reverse of heat engine operate?
carnot engine
What is meant by Carnot cycle?
The Carnot cycle is a mathematical description of an engine that derives its power from heat.
What did Sadi Carnot invent?
Sadi Carnot did not invent anything. He was a French engineer and physicist who formulated the principles of thermodynamics and is considered one of the founders of thermodynamic theory.
Why you learn carnot cycle while it is not use in reality?
because it is the best theoretical engine. our aim is always to make our practical engine as close as that of carnot. if u don't know about the carnot cycle then how will u do that.
What is known as carnot heat engin?
carnot's heat heat engine is also known as ideal heat engine.because in carnot's the precess is reversible .Total heat converted into work . The efficiency is maximum for carnot's heat engine.
Define the efficiency of carnot engine?
The efficiency of the carnot engine - or any engine for that matter - is given by the quocient between the desired effect and what you payed for it, that is, the quocient between the net work output and the heat added to the system.
