Antoine Equation

Written by Jerry Ratzlaff on . Posted in Thermodynamics

Antoine equation is the relationship between vapor pressure and the temperature of pure substances.

 

Antoine equation Formula

\(\large{ log_{10} \;p = A - \frac{ B }{ C\;+\;T }  }\)   

Where:

 Units English Metric
\(\large{ p  }\) = vapor pressure \(\large{\frac{lbf}{in^2}}\) \(\large{\frac{kg}{m-s^2}}\)
\(\large{ T  }\) = temperature \(\large{ F }\) \(\large{ C}\)
\(\large{ A, B, C  }\) = component specific constants dimensionless
