2. at o°c, air can contain
4.85 g/m² of water vapor.
assume the actual water
vapor content is 0.97 g/m3.
what is the rh?

RH = 20%

Explanation:

Data given:

water pressure at 0°C  = 4.85 g/m³

Actual water vapor density = 0.97 g/m³

Relative humidity (RH) = ?

Solution:

Formula used

       Relative humidity (RH) =    x 100%

As we know that at 0°C water vapor have 4.85 g/m³ saturated vapor density.

So,

put values in the above formula

     Relative humidity (RH) =  0.97 g/m³ /  4.85 g/m³ x 100%

     Relative humidity (RH) =  0.2 x 100%

     Relative humidity (RH) = 20%

So,  

Relative humidity (RH) = 20%
