Webreversibility, in thermodynamics, a characteristic of certain processes (changes of a system from an initial state to a final state spontaneously or as a result of interactions with other systems) that can be reversed, and the system restored to its initial state, without leaving net effects in any of the systems involved. An example of a reversible process would be a … WebThis is a first-level course in thermodynamics, aimed at UG first and second year students. The syllabus closely follows the AICTE model syllabus in thermodynamics. At the end of the course, students would be expected to be able to demonstrate an understanding of the laws of thermodynamics and solve problems involving heat and work interactions, with various …
WebIn thermodynamics, an irreversible process is defined as a process that cannot be reversed, which cannot return both the system and the surroundings to their original conditions. … WebIn the irreversible process, the system receives heat and does work .

WebFeb 2, 2011 · Figure 1 shows the idealized Rankine cycle. The pressure-enthalpy (p-h) and temperature-entropy (T-s) diagrams of this cycle are given in Figure 2. The Rankine cycle operates in the following steps: 1-2-3 Isobaric Heat Transfer. High pressure liquid enters the boiler from the feed pump (1) and is heated to the saturation temperature (2).
In science, a process that is not reversible is called irreversible. This concept arises frequently in thermodynamics. All complex natural processes are irreversible, although a phase transition at the coexistence temperature (e.g. melting of ice cubes in water) is well approximated as reversible.
