Answer:
Relative humidity of a sample is 31%
Explanation:
Difference in temperature = dry bulb - wet bulb
[tex]T_{db} - T_{wb}[/tex]
= 20 -11
= 9
Look at the table for :
[tex]T_{db} - T_{wb}[/tex] = 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.
