Reduced Equation of State
reduced equation of state
[ri′düst i′kwā·zhən əv ′stāt]Reduced Equation of State
an equation relating the reduced parameters of a thermodynamic equilibrium system, that is, the parameters of pressure, volume, and temperature, defined as the ratio of their values to the critical state. The reduced equation of state is quite general; for example, it is identical for all gases, since it does not contain the physicochemical constants that characterize individual gases.
