Reversibility and Irreversibility
These two concepts are highly important for the thermodynamic processes and systems. Reversibility is defined as an operator that, as a system and its surroundings can be returned in original condition, are merely theoretical. Irreversibility shows the destruction of the availability and argues that both the system and its surroundings cannot be returned in original condition of irreversibilities taking place, for example, friction, heat, and electrical and mechanical effects.
For example, as a real system provides the amount of work that is less than the ideal reversible work, the difference between these two values gives the irreversibility of this system. In a real application, there are always differences, and hence, the real cycles always irreversible. For example, entropy, heat given off in the condenser is always more than warmly accepted in the evaporator, referring to the fact that the entropy always increases through the functioning of a real system of cooling...
