Relative Humidity

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

Relative humidity, abbreviated as RH, is a measure of the amount of moisture in the air with respect to the temperature.

 

Relative Humidity formulas

\(\large{ RH = 100 \; \frac{e}{e_s}  }\)   
\(\large{ RH = 100 \;  \left(  \frac{ 112 \; - \; 0.1 \; T \; + T_d }{ 112 \; + \; 0.9 \; T }   \right)^8   }\)   

Where:

\(\large{ RH }\) = relative humidity

\(\large{ e }\) = actual vapor pressure

\(\large{ T_d }\) = dewpoint temperature

\(\large{ e_s }\) = saturated vapor pressure

\(\large{ T }\) = temperature
