The Clausius theorem, also known as the Clausius inequality, ... This is because in a cyclic process the variation of a state function is zero per cycle, ...
The Clausius theorem (1854) states that in a cyclic process The equality holds in the reversible case [68] and the strict inequality holds in the irreversible case, with T surr as the temperature of the heat bath (surroundings) here.
A cyclic process is one that can be repeated indefinitely often, returning the system to its initial state. Of particular interest for single cycle of a cyclic process are the net work done, and the net heat taken in (or 'consumed', in Clausius' statement), by the system.
Rudolf Julius Emanuel Clausius (German pronunciation: [ˈʁuːdɔlf ˈklaʊzi̯ʊs]; [1] [2] 2 January 1822 – 24 August 1888) was a German physicist and mathematician and is considered one of the central founding fathers of the science of thermodynamics. [3]
If the cyclic process moves clockwise around the loop, then will be positive, the cyclic machine will transform part of the heat exchanged into work and it represents a heat engine. If it moves counterclockwise, then W n e t {\displaystyle W_{net}} will be negative, the cyclic machine will require work to absorb heat at a low temperature and ...
The figure at right shows a block diagram of a generic heat engine, such as the Carnot engine. In the diagram, the "working body" (system), a term introduced by Clausius in 1850, can be any fluid or vapor body through which heat Q can be introduced or transmitted to produce work. Carnot had postulated that the fluid body could be any substance ...
Most heat engines and refrigerators are closed cyclic ... This is the Clausius statement of the second law. ... "Entropy production fluctuation theorem and the non ...
Cyclic processes were important conceptual devices in the early days of thermodynamical investigation, while the concept of the thermodynamic state variable was being developed. (3) Defined by flows through a system, a flow process is a steady state of flows into and out of a vessel with definite wall properties.
