Systems
When a closed system undergoes a change of its equilibrium from a begin-State to a finish-State, it is called a Closed Process in TEST. Furthermore, if the state of the system, at a given instant, can be described by a single State, the system is called uniform. An Analysis layer is added to the States layer to solve the mass, energy and entropy balance equations. After evaluating the anchor states fully or partially, you import them to the Analysis panel, enter the known process variables, and Calculate up to three unknowns. A Super-Calculate iterates between the State and Analysis panels to produce the desired unknowns. |

| Exergy
Analysis
After a process analysis is complete, an exergy (availability) analysis is really simple. You evaluate the dead-state and import it to the Exergy panel, where all the exergy related variables are calculated and displayed. In a what-if study, when you change a variable and update all calculations using the Super-Calculate button, the Exergy panel is also updated. |

Mixing Systems
Two unique States are required to describe the begin-State while at the end of the process a single State suffices to describe the f-State. The mixing between two gases contained in two tanks, the free expansion of a working fluid from one chamber to an evacuated chamber are examples of non-uniform mixing systems. |

Non-Mixing Systems
Two unique States are required to describe the begin-State and two unique States are required to describe the finish-State as well as the system remains non-uniform at the end of the process. Heat exchange between a block of copper dropped into a jar of water belongs to this category if the control volume includes both copper and water. |
