What is meant by quasi-static?
Solution. A quasi-static process is an infinitely slow process in which the system changes its variables (P, V, T) so slowly such that it remains in thermal, mechanical, and chemical equilibrium with its surroundings throughout.
What is the difference between quasi-static and reversible process?
To summary, quasistatic process is the process in which every instantaneous states is equilibrium;reversible process is the quasistatic process in which the entropy does not increase,but the quasistatic is not necessarily a reversible, that depents on the entropy—increasing or not.
What is meant by quasi-equilibrium process?
A quasi-equilibrium process is one in which the system remains very nearly at equilibrium at all times during the process. The process can be represented by a line on a P-V or T-S diagram, which makes the process much simpler to visualize and to analyze.
What is quasi-static process class 11?
A quasi-static process (also known as a quasi-equilibrium process) is a type of thermodynamic process. Quasi-static expansion is an example of this, in which the volume of a system changes so slowly that the pressure remains constant throughout the system at all times during the process.
What is quasi-static process explain its importance engineering?
It can be defined in simple words that it is the process happening very slowly, and all state passed by this process is in equilibrium. This process is always reversible in nature. There is no friction or loss present. It is not realized for any finite difference of the system.
What is a quasi-static reversible process?
A process, carried out in a stepwise manner, becomes quasi-static when the number of intermediate steps tends to infinity. Usually, the net entropy production approaches zero under this limiting condition. Hence, such cases are termed reversible.
Why quasi-static process is reversible?
What is quasi-static process BYJU’s?
Quasi-static process is called a slow process in thermodynamics. It is a process that occurs infinitesimally slow. All the states in a quasi-static process are in equilibrium.
What is quasi-static process in mechanical engineering?
When a process is processing in such a way that system will be remained infinitesimally close with equilibrium state at each time, such process will be termed as quasi static process or quasi equilibrium process.
Is quasi-static process always reversible?
whereas, a quasi-static process is a kind of process which takes place very slowly, by doing so it is possible some time to be considered as a reversible process but not always in some cases only. Quasi-static process is not always reversible.
