Mixing Closed Process and Its Governing Balance Equations
System 
Animation of a closed non-uniform system going through a mixing process. The beginning-state is composed of two states bA and bB states (non-uniform). As the valve between the two chambers is opened and the two working fluids (can be the same fluid at two different state) are allowed to mix, equilibrium is finally achieved, resulting in a single f-state (fully mixing). Although the system is closed, as indicated by the red system boundary, the sub-systems are clearly open and much harder to analyze. For specific examples of mixing closed processes, visit TEST.Animations.Chapter-5 pages.
