Saturated Vapor Pressure

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	\(\large{\frac{lbf}{in^2}}\)	\(Pa\)
