What is a quasi equilibrium. What is its importance in engineering?

When a process proceeds in such a manner that the system remains infinitesimally close to an equilibrium state at all times, it is called a quasi-static or a quasi-equilibrium process. A quasi-equilibrium process can be viewed as a sufficiently slow process that allows the system to adjust itself internally so that properties on one part of the system do not change any faster than those other parts. Engineers are interested in quasi-equilibrium process for two reasons. Firstly, they are easy to analyze. Secondly, work-producing devices deliver the most work when they operate on quasi-equilibrium processes. Engineer Ebrahim Anwar Kisswani.


Is internal equilibrium from quasi equilibrium?

No, internal equilibrium is not the same as quasi equilibrium. Internal equilibrium refers to a system being in a state where there is no net change in composition, while quasi equilibrium refers to a process that occurs almost at equilibrium, but not necessarily at the exact equilibrium point.


Slow compression of a gas in a piston cylinder assembly is approximated as a quasi equilibriium process while fast compression of the same gas is classified as non quasi equilibrium process?

quasi equilibrium is reached when molecules of gas comes at same temperature n time is required for this...


What is the definition of quasi-static and how does it relate to the behavior of systems in a state of near equilibrium?

Quasi-static refers to a process that happens slowly enough that it can be considered almost static. In systems near equilibrium, quasi-static processes allow for small changes to occur without causing significant disturbances. This helps in analyzing and understanding the behavior of systems in a state of near equilibrium.


What is the significance of the quasi-static process in thermodynamics and how does it differ from dynamic processes?

The quasi-static process in thermodynamics is important because it allows for the system to be in equilibrium at every step, making it easier to analyze and calculate. This process differs from dynamic processes, which happen quickly and may not allow the system to reach equilibrium at each step.


What is quasi static process?

A quasi-static process is a thermodynamic process that occurs very slowly, allowing the system to remain in equilibrium at all times. It is often used in thermodynamics to simplify calculations by assuming that the system is always in equilibrium, even though the process is not truly reversible. This approach helps in analyzing the properties and behavior of the system more easily.


What does the term "quasi-static" refer to in the context of physics or engineering?

In physics and engineering, the term "quasi-static" refers to a process or system that changes very slowly compared to the time scales of interest, allowing for simplification of calculations and analysis.


What are the characteristics and applications of a quasi-static process in thermodynamics?

A quasi-static process in thermodynamics is a slow and gradual change in a system, where the system remains in equilibrium at every step. This allows for accurate measurements and calculations. Quasi-static processes are often used in thermodynamic analysis, such as in the study of heat engines and refrigeration systems.


In carnot's heat engine why is the heating done at extremely slow rate?

Yes , its a quasi equilibrium process so heat is added slowly


Can you define the concept of quasi-static in the context of physics and engineering?

Quasi-static refers to a process that happens slowly enough that it can be considered as if it were happening at a constant rate. In physics and engineering, this concept is used to simplify calculations and analysis of systems that change gradually over time.


What is the concept of quasi-static and how does it relate to the behavior of systems in thermodynamics?

Quasi-static refers to a process that happens slowly and smoothly, allowing the system to be in equilibrium at every step. In thermodynamics, systems behave predictably under quasi-static conditions, making it easier to analyze and understand their behavior.


An example of quasi static process?

Quasi static process - doesn't really exist except in theory. It is a thermodynamic process going infinitely slow. The best example is if you had air at 1C inside a cryogenic thermos and you had add outside the thermos at 1.00000000000001C. The point is is the air inside the thermos would eventually warm up to the slightly warmer air outside the container, but it would take a long long time.
