Why is the Carnot engine not possible?

Why is the Carnot engine not possible?

In real engines, the heat transfers at a sudden change in temperature whereas in a Carnot engine, the temperature remains constant. In our day to day lives, reversible processes can’t be carried out and there is no such engine with 100 \% efficiency. Thus, the Carnot cycle is practically not possible.

Can we make Carnot cycle engine?

A Carnot heat engine is a theoretical engine that operates on the Carnot cycle. The system may be worked upon by an external force, and in the process, it can transfer thermal energy from a cooler system to a warmer one, thereby acting as a refrigerator or heat pump rather than a heat engine.

What are the limitations of Carnot engine?

 The higher the temperature of the low- temperature sink, the more difficult for a heat engine to transfer heat into it. Thus, lower thermal efficiency also. 16. LIMITATIONS OF CARNOT CYCLE  The isentropic process 1-2 is practically not achievable,as it is difficult to handle two phase system.

Is Carnot engine a real engine?

A Carnot engine is a theoretical engine that operates on the Carnot cycle. Nicolas Leonard Sadi Carnot developed the basic model for this engine in 1824.

What are the limitations of reversed Carnot refrigeration cycle?

Reversed Carnot refrigeration cycle with liquefaction and vaporization of the refrigerant. There are two major drawbacks to the reversed Carnot cycle with phase-change refrigerant: 1. The adiabatic compression between Tlow and Thigh occurs in the liquid–vapor region, which is why it is called wet compression.

Which type of engine is Carnot engine?

heat engine
What is Carnot Engine? Carnot engine is a theoretical thermodynamic cycle proposed by Leonard Carnot. It estimates the maximum possible efficiency that a heat engine during the conversion process of heat into work and, conversely, working between two reservoirs can possess.

What is the Carnot engine efficiency?

The Carnot Efficiency is the theoretical maximum efficiency one can get when the heat engine is operating between two temperatures: The temperature at which the high temperature reservoir operates ( THot ). The temperature at which the low temperature reservoir operates ( TCold ).

Can you design a heat engine of 100 efficiency?

It is impossible for heat engines to achieve 100\% thermal efficiency () according to the Second law of thermodynamics. This is impossible because some waste heat is always produced produced in a heat engine, shown in Figure 1 by the term.
