In thermodynamics, equivalence-value of all uncompensated transformations, symbol N, is defined by the following expression:
which is the quantitative measure of the "equivalence-values", or mechanical equivalent of heat changes associated with internal irreversible work process that exist at the end of one cyclical process or what are called "uncompensated transformations". This name "equivalence-value of all uncompensated transformations" was an early extended synonym for what would famously become termed as "entropy" in 1865.
The nature of this variable N was addressed in Rudolf Clausius in his 1854-56 “principle of the equivalence of transformations”.
