Reduced properties

Reduced properties refer to the ratio of the actual value of a physical property to its critical value, which is used to relate these values to actual physical properties. These properties are specifically defined as such and are often referred to as reduced properties.From: Chemical Thermodynamics [2019], Study of Falling Condensate Droplets on Parallelepiped Solid Surface Using Hybrid 3D MRT-LBM [2022], Handbook of Petroleum Refining [2019]

The behavior of widely different materials can be brought to the same basis by invoking the principle of corresponding states, according to which reduced properties of gases and liquids follow the same relationships with reduced pressure and temperature. Reduced means that the value is normalized by dividing it by its value at the critical point. The reduced temperature and pressure can be interpreted as measurements of the deviation from ideal gas behavior, and hence of the interaction between molecules. Figure 1.4 plots reduced viscosity for many gases and liquids against reduced pressure and temperature.

The critical parameters are given by The critical density is and the critical temperature is being expressed in lattice units. To relate these values to actual physical properties, we use the concept of reduced properties. The subscripts ‘’ and ‘’ stand for reduced and critical properties respectively. According to the law of corresponding states, the reduced properties must be the same whatever the type of units used, i.e.
