Reduced properties

  • in thermodynamics, the reduced properties of a fluid are a set of state variables scaled by the fluid's state properties at its critical point. these dimensionless thermodynamic coordinates, taken together with a substance's compressibility factor, provide the basis for the simplest form of the theorem of corresponding states.[1]

    reduced properties are also used to define the peng–robinson equation of state, a model designed to provide reasonable accuracy near the critical point.[2] they are also used to critical exponents, which describe the behaviour of physical quantities near continuous phase transitions.[3]
