The Carnot Heat Engine Cycle and the Carnot Heat Pump Cycle are reversible cycles and do not exist in any actual operation. However, they are very useful

for predicting maximum possible thermal efficiencies and coefficients of performance using the absolute temperature of the heat source and the absolute temperature of the heat sink. The Carnot Cycle consists of two reversible and adiabatic ( isentropic ) steps and two reversible and isothermal steps.

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.

What makes a Carnot cycle unique?

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.


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


Which cycle is best in heat engine?

The ideal cycle for a heat engine is often considered to be the Carnot cycle, as it provides the maximum possible efficiency between two temperature reservoirs. This theoretical cycle operates through four reversible processes: two isothermal and two adiabatic. Although real engines cannot achieve Carnot efficiency due to practical limitations and irreversibilities, the Carnot cycle serves as a benchmark for evaluating the performance of actual heat engines. Other cycles, like the Otto or Diesel cycles, are commonly used in practice, but they are less efficient than the Carnot cycle.


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.

Why refrigeration cycle is called reverse carnot cycle?

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.
