The theory developed by Onsager is much more general than this example and capable of treating more than two thermodynamic forces at once. In thermodynamics, the Onsager reciprocal relations express the equality of certain ratios between flows and forces in thermodynamic systems out of equilibrium, but where a notion of local equilibrium exists. "Reciprocal relations" occur between different pairs of forces and flows in a variety of physical systems. For example, consider fluid systems described in … raynor garage door bottom seal replacement

WebFrom this, the conjugate fluxes and affinities are directly obtained and the transport equations written using these quantities. The Onsager relations are applied to the kinetic coefficients defined in the transport equations and, after further manipulations, the experimental transport parameters may be found in terms of these quantities. WebIn this region, the transport and rate equations are expressed in linear forms, and the Onsager reciprocal relations are valid. Therefore, sometimes this region is called the linear or Onsager region and the formulations are based on linear nonequilibrium thermodynamics theory.
