Question

Give a explanation of the Carnot cycle in words. Include examples of how it is useful. Propose a system that could be represented by a Carnot cycle.

Answer 1

Carnot engine is a theoretical engine on or it is ideal engine or it is reference engine or it is reversible engine and carnot engine is practically impossible engine because during cost temperature process the engine should run very slowly and during reversible adibatic process engine should run very fastly and in universe there is no such mechanism which will run engine very fastly slowly alternatively

2)also cost temp process the engine material acts as perfect conductors and during reversible adibatic process and same engine material acts as perfect insulators and in universe there is no such material which will acts as perfect as insulation and conductors alternatively therefore carnot engine practically impossible

1-2 isothermal heat supply

2-3 reversible adibatic expansion

3-4 isothermal heat rejection

4-1 reversible adibatic compression

How it's useful?

However, since the Carnot cycle represents the maximum possible thermal efficiency of a heat engine operating within given temperature limits, it is often useful to evaluate real engines in the context of their theoretical maximum efficiency, or to know what the theoretical maximum efficiency is during design.
