reversible.But always remember that a carnot cycle is an idealized cycle and it is not
the Carnot cycle has 2 constant specific volume processes (heat in & heat out) the air refrigeration cycle is based on a brayton cycle which has two constant pressure processes.
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.
The Carnot cycle is an idealized thermodynamic cycle that describes a perfect heat engine. In the Refrigeration system we need cooling effect.so it has to operate in opposite nature to produce the cooling effect. So we run the catnot cycle reversly in the refrigeration system. So we call the Refrigeration cycle called as REVERSED CARNOT CYCLE.
carnot cycle?
carnot cycle is the highiest efficiency
What is the difference between ideal and actual cycle?
The Carnot cycle is a mathematical description of an engine that derives its power from heat.
The Carnot cycle was proposed by Nicolas L©onard Sadi Carnot in 1823. It is a theoretical thermodynamic cycle. It is the most efficient cycle for creating a temperature difference.
The Carnot Cycle is a prime example of what is possible under the laws of physics however the cycle is impractical to build. The facts that its keeps stepping back and forth from isothermal to adibatic processes make it very hard to construct.
no, a Carnot cycle is not practiclly possible.bcz carnot consist of two cycles. i.e 1-rev. adiabatic 2-isothermal
Rankine cycle allows for practical implementation with real working fluids such as water, making it more feasible for thermal power plants compared to the idealized Carnot cycle. Rankine cycle also allows for the use of turbines and pumps which are more efficient than isothermal expansion and compression processes in the Carnot cycle. Additionally, Rankine cycle can be modified with reheating and regeneration to improve efficiency further, something the Carnot cycle cannot achieve.
The Carnot power cycle is based on four key principles: reversible isothermal expansion, reversible adiabatic expansion, reversible isothermal compression, and reversible adiabatic compression. The cycle involves transferring heat energy from a high-temperature reservoir to a working fluid, which then performs work by expanding and contracting. The efficiency of the Carnot cycle is determined by the ratio of the temperatures of the hot and cold reservoirs.
