Question

Are heat engines reversible?

Answer 1

Hint : Each reversible warmness engine working between the equal temperature reservoirs has the same efficiency. This indicates regardless of how a reversible warmth engine is built or what the working fluid is, its performance is the same as all different warmth engines working from the identical two temperatures.

Complete Step By Step Answer:
In thermodynamics and engineering, a heat engine is a device that converts warmth or thermal energy to mechanical electricity, which can then be used to do mechanical paintings. It does this by bringing an operating substance from a better country temperature to a decreased country temperature.
A warmness source generates thermal electricity that brings the running substance to a high-temperature state. The operating substance generates paintings within the operating frame of the engine whilst moving heat to the chillier sink till it reaches a low-temperature kingdom. In the course of this technique, some of the thermal power is transformed into paintings with the aid of exploiting the houses of the operating substance.
The running substance may be any gadget with a non-0 heat ability; however, it commonly is fuel or liquid. During this system, a few heats are generally misplaced in the environment and aren’t transformed into paintings. Additionally, some strength is unusable because of friction and drag. In trendy, an engine converts strength to mechanical paintings. warmness engines distinguish themselves from other sorts of engines via the fact that their performance is essentially restrained by using Carnot's theorem.]

Note :
The amount of warmth converted into paintings in a warmness engine is always greater in a reversible technique than in an irreversible technique. all of the different cycles of the heat engine are primarily based on the Carnot engine only. As a result, it's far used to evaluate the effects of different cycles.
