Reduced properties are also used to define the
Reduced pressure
The reduced pressure is defined as its actual pressure divided by its
Reduced temperature
The reduced temperature of a fluid is its actual temperature, divided by its
where the actual temperature and critical temperature are expressed in absolute temperature scales (either Kelvin or Rankine). Both the reduced temperature and the reduced pressure are often used in thermodynamical formulas like the Peng–Robinson equation of state.
Reduced specific volume
The reduced specific volume (or "pseudo-reduced specific volume") of a fluid is computed from the ideal gas law at the substance's critical pressure and temperature:[1]
This property is useful when the specific volume and either temperature or pressure are known, in which case the missing third property can be computed directly.
