Thus, reversible processes can easily be defined as idealizations or models of real processes on which the limits of the system or device are to be defined. They help us in incurring the maximum efficiency a system can provide in ideal working conditions and, thus, the target design that can be set


What is the function of a reversible process?
A reversible process in engineering is a theoretical concept where a system changes from its initial state to a final state in such a manner that both the system and its surroundings can be returned to their original conditions. The process occurs infinitely slowly and is not feasible in real-world operations.

What is required for a reversible process?
Reversible processes require the absence of friction or other hysteresis effects. They must also be carried out infinitesimally slowly. Otherwise pressure waves and finite temperature gradients will be set up in the system, and irreversible dissipation and heat flow will occur.

What is the necessary condition for a reversible process?
The substance undergoing a reversible change must at all instances be in thermodynamic equilibrium with its surroundings. All the processes taking place in the cycle of operation must be infinitely slow.

What is the significance of reversibility?
Reversibility in engineering processes is significant because it represents an ideal process without losses due to friction, deformation, or other inefficiencies.

Summary. A reversible process is one in which both the system and its environment can return to exactly the states they were in by following the reverse path. An irreversible process is one in which the system and its environment cannot return together to exactly the states that they were in.




What is reversibility in thermodynamics?
reversibility, in thermodynamics, a characteristic of certain processes (changes of a system from an initial state to a final state spontaneously or as a result of interactions with other systems) that can be reversed, and the system restored to its initial state, without leaving net effects in any of the systems .



What is the difference between a reversible and irreversible reaction?
A reversible reaction is in when forward and reverse directions of the reaction occur at the same rate so there is no overall change in the amounts of reactants and products. Irreversible chemical reactions can occur in only one direction



What is the difference between irreversibility and reversibility?
A reversible process is one in which both the system and its environment can return to exactly the states they were in by following the reverse path. An irreversible process is one in which the system and its environment cannot return together to exactly the states that they were in.
