What is relative humidity of a sample of air that has a dry bulb temperature of 20 and a wet bulb temperature of 11

Relative humidity of a sample is 31%

Explanation:

Difference in temperature = dry bulb - wet bulb

= 20 -11

= 9

Look at the table for :

= 9 and T(dry) = 20

Relative Humidity : It is ratio of actual mass of water vapour in a given moist air to the mass of water vapour in the same volume of saturated air at the same temperature and pressure. It is written as RH.
