FAQs on Reversible & Irreversible Process Video Lecture - Thermodynamics - Mechanical Engineering

1. What is a reversible process in thermodynamics?

Ans. A reversible process in thermodynamics is a hypothetical process that can be reversed by an infinitesimal change in the system's parameters, resulting in no change in the surroundings. It is an idealized concept that allows for the analysis of thermodynamic systems under ideal conditions.

2. What is an irreversible process in thermodynamics?

Ans. An irreversible process in thermodynamics is a process that cannot be reversed by any means without producing some change in the surroundings. It involves the generation of entropy and results in an overall loss of useful energy. Most real-world processes are irreversible due to factors like friction, heat transfer, and fluid flow resistance.

3. How is a reversible process different from an irreversible process?

Ans. In a reversible process, the system and surroundings can be brought back to their initial states by reversing the process with infinitesimal changes. On the other hand, an irreversible process cannot be reversed without affecting the surroundings and results in a net increase in entropy. Reversible processes are idealized concepts, while irreversible processes are more representative of real-world scenarios.

4. What are some examples of reversible processes?

Ans. Some examples of reversible processes include a pendulum swinging with no friction, a gas expanding or compressing in a frictionless cylinder, and an idealized heat engine operating between two heat reservoirs at different temperatures without any energy loss. These processes are hypothetical and do not exist in practice but are useful for theoretical analysis.

5. Why are reversible processes important in thermodynamics?

Ans. Reversible processes are important in thermodynamics because they provide an idealized framework for understanding the behavior of thermodynamic systems. They allow for the calculation of maximum work output and efficiency, and serve as a benchmark for comparing real-world processes. Although reversible processes are not attainable in practice, they provide valuable insights into the limits and principles of thermodynamics.
