Are all reversible engines Carnot?

The same proof can be run through with the reversible engine as more efficient and again there is a violation. This means all reversible engines are of the same efficiency as Carnot engines.

Is the Carnot cycle the only reversible cycle?

The Carnot cycle is not the only possible reversible process. It is famous because historically, the idea of the Carnot cycle crystallized the concept of reversible vs. irreversible processes.

Is a reversible engine possible?

Reversible heat engines operating between two heat reservoirs have the same thermal efficiency that depends only on the temperatures of the two heat reservoirs regardless of the working fluids, and no heat engine can exceed this thermal efficiency.

Which engine is reversible?

Carnot engine
, in this process. . For the Carnot engine, the entire process is ‘reversible’, and Equation (7) is an equality.

Is Ericsson cycle reversible or irreversible?

Carnot, Ericsson and Stirling cycles are ideal power cycles that are completely reversible. 2.

Is Carnot engine 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.

Is there a real Carnot engine?

While Carnot engines are ideal engines, in reality, no engine achieves Carnot’s theoretical maximum efficiency, since dissipative processes, such as friction, play a role. Carnot cycles without heat loss may be possible at absolute zero, but this has never been seen in nature.

What is reversible and irreversible engine?

The efficiency of the reversible engine is greater than the irreversible engine. Reversible engines are the ones that can be reversed or whose process if reversed will not cause any loss of energy. For example the Carnot cycle. Irreversible engines are the ones that undergo loss of energy in due course of operation.

Are Stirling engines practical?

Also, Stirling engines do not use explosions like normal gasoline engines, therefore they are very quiet. Although these seem like major advantages to an ordinary engine, they are less practical in most vehicles because they require external heat, rather than internal heat.

Is Otto cycle a reversible cycle?

The Otto cycle is another example of a reversible cycle that only exists in theory. We study the Otto cycle to understand what takes place inside the internal combustion engine. The Otto cycle consists of four reversible processes, two being adiabatic processes and two being isovolumetric processes.
