The path between each state consists of some process (A through D) which alters the pressure or volume of the system (or both). Generalized PV diagram. A key feature of the diagram is that the amount of energy expended or received by the system as work can be measured because the net work is represented by the area enclosed by the four lines ...
The block diagram can use additional schematic symbols to show particular properties. Since the late 1950s, functional block diagrams have been used in a wide range applications, from systems engineering to software engineering. They became a necessity in complex systems design to "understand thoroughly from exterior design the operation of the ...
The PV diagram is a particularly useful visualization of a quasi-static process, because the area under the curve of a process is the amount of work done by the system during that process. Thus work is considered to be a process variable , as its exact value depends on the particular path taken between the start and end points of the process.
The pressure on a pressure-temperature diagram (such as the water phase diagram shown above) is the partial pressure of the substance in question. A phase diagram in physical chemistry , engineering , mineralogy , and materials science is a type of chart used to show conditions (pressure, temperature, etc.) at which thermodynamically distinct ...
Example of a system context diagram. [1] A system context diagram in engineering is a diagram that defines the boundary between the system, or part of a system, and its environment, showing the entities that interact with it. [2] This diagram is a high level view of a system. It is similar to a block diagram.

A saturation dome uses the projection of a P–v–T diagram (pressure, specific volume, and temperature) onto the P–v plane. The points that create the left-hand side of the dome represent the saturated liquid states, while the points on the right-hand side represent the saturated vapor states (commonly referred to as the “dry” region).
"The obtained numerical models were developed using the program Surface-water Modeling System (SMS) v.10.1.11, which was designed by experts from Aquaveo company. The hydrodynamics of the studied sector, obtained using the SMS module named RMA2 [13], served as input for the RMA module 4, which determined the pollutant dispersion" (Marusic and ...
