Saturated Vapor Pressure

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

Saturated vapor pressure, abbreviated as \(e_s\), is the pressure applied by air that is mixed with water vapor, at a given temperature, at its maximum saturation point.

 

Saturated Vapor Pressure formula

\(\large{ e_s = 100 \; \frac{RH}{e}  }\)   

Where:

 Units English Metric
\(\large{ e_s }\) = saturated vapor pressure \(\large{\frac{lbf}{in^2}}\) \(\large{\frac{kg}{m-s^2}}\)
\(\large{ e }\) = actual vapor pressure \(\large{\frac{ft-lbf}{lbm-R}}\)  \(\large{\frac{J}{kg-K}}\) 
\(\large{ RH }\) = relative humidity \(\large{\frac{lbf}{in^2}}\) \(Pa\)
