The Acentric Factor calculator computes the factor based on the reduced pressure.
INSTRUCTIONS: Enter the following:
Acentric Factor (ω): The factor is returned as a real number
The Acentric Factor equation computes the acentric factor (`omega`)[1], a measure of the non-sphericity of molecules.
The acentric factor characterizes the phase of gases. The acentric factor computed here is a function of the reduced pressure at the reduced temperature, `T_r` = 0.7. The acentric factor, `omega`, is one of the set of state description parameters that includes: molecular weight, critical temperature, critical pressure, and critical volume.
The reduced properties of fluids are a set of state variables which are normalized by the fluid's state properties at the fluid's critical point. In this equation two reduced properties are used:
