Work Interaction Work is an interaction between two systems such that whatever happened in each system and its boundary could be repeated exactly while the sole external effect is a change of level of a weight. Measure of work The work of a system equals the number of weights, in the test, that und ...

ONSAGER`S VARIATIONAL PRINCIPLE AND ITS APPLICATIONS
... S = S(U, xν , Ni ). We consider the condition for equilibrium in a system made up of two interconnected subsystems, as illustrated in figure 1. Initially the subsystems are separated from each other by a insulating, rigid, and non-permeable barrier. Weakly interacting quasi-closed subsystems: In the ...

Rankine cycle analysis 5
... The Rankine cycle is the most common of all power generation cycles and is diagrammatically depicted via Figures 1 and 2. The Rankine cycle was devised to make use of the characteristics of water as the working fluid. The cycle begins in a boiler (State 4 in figure 1), where the water is heated unti ...
