An example of this is quasi-static expansion of a mixture of hydrogen and oxygen gas, where the volume of the system changes so slowly that the pressure remains uniform throughout the system at each instant of time during the process. [2] Such an idealized process is a succession of physical equilibrium states, characterized by infinite ...
Quasistatic approximation(s) refers to different domains and different meanings. In the most common acceptance, quasistatic approximation refers to equations that keep a static form (do not involve time derivatives) even if some quantities are allowed to vary slowly with time. In electromagnetism it refers to mathematical models that can be ...
The repeating nature of the process path allows for continuous operation, making the cycle an important concept in thermodynamics. Thermodynamic cycles are often represented mathematically as quasistatic processes in the modeling of the workings of an actual device.
Reversible processes are always quasistatic, but the converse is not always true. [2] For example, an infinitesimal compression of a gas in a cylinder where there is friction between the piston and the cylinder is a quasistatic , but not reversible process. [ 7 ]
A quasistatic process is an idealized or fictive model of a thermodynamic "process" considered in theoretical studies. It does not occur in physical reality. It does not occur in physical reality. It may be imagined as happening infinitely slowly so that the system passes through a continuum of states that are infinitesimally close to equilibrium .
Quasistatic can refer to: Quasistatic process; Quasistatic equilibrium; Quasistatic loading; Quasistatic approximation This page was last edited on ...
This free expansion is irreversible but can be quasi-static for each chamber: quasi-equilibrium is retained for each part but not for the whole system The Joule expansion (a subset of free expansion ) is an irreversible process in thermodynamics in which a volume of gas is kept in one side of a thermally isolated container (via a small ...
