What is the use of Acentric factor?
It has become a standard for the phase characterization of single & pure components. The other state description parameters are molecular weight, critical temperature, critical pressure, and critical volume (or critical compressibility). The acentric factor is said to be a measure of the non-sphericity (centricity) of molecules. As it increases, the vapor curve is "pulled" down, resulting in higher boiling points.
How to Calculate Acentric Factor?
Acentric Factor calculator uses Acentric Factor VP = -log10(Reduced saturation vapour pressure)-1 to calculate the Acentric Factor VP, The Acentric Factor formula is defined as a standard for the phase characterization of single & pure components. The other state description parameters are molecular weight, critical temperature, critical pressure, and critical volume (or critical compressibility). Acentric Factor VP is denoted by ωvp symbol.
How to calculate Acentric Factor using this online calculator? To use this online calculator for Acentric Factor, enter Reduced saturation vapour pressure (Prsaturated) and hit the calculate button. Here is how the Acentric Factor calculation can be explained with given input values -> -1.70757 = -log10(5.1)-1.
