The dew point temperature is 11.486. When temperatures fall below the b, moisture capacity decreases.
Under constant air pressure and water content, the dew point is the temperature at which air must be chilled to become saturated with water vapor.
When temperatures fall below the dew point, moisture capacity decreases and airborne water vapor condenses to create liquid water known as dew.
The dew point temperature is found as;
[tex]\rm T_d = T - ((100 - \frac{R_H}{5} )\\\\ \rm T_d = 20 - ((100 - \frac{58}{5} )\\\\T_d=11.486^0 C[/tex]
Hence, the dew point temperature will be 11.486 °C
