# Saturated Vapor Pressure

Written by Jerry Ratzlaff. Posted in Fluid Mechanics

Saturated vapor pressure is the pressure applied by air that is mixed with water vapor, at a given temperature, at its maximum saturation point.

## formula

$$e_s = 100 \frac{\phi}{e}$$

Where:

$$e_s$$ = saturated vapor pressure

$$\phi$$ = relative humidity

$$e$$ = actual vapor pressure
