Determination of relative humidity by wet and dry bulb hygrometer

 

Experiment Name:  Determination of relative humidity by wet and dry bulb hygrometer.

Objective:

i) To know about relative humidity.

II) To know about principle process of wet and dry bulb hygrometer.

III) To determinate relative humidity exists in our textile testing and quality control lab.

IV) To write a brief report according to this experiment.

Relative Humidity: Relative humidity (abbreviated RH) is the ratio of the partial pressure of water vapour to the equilibrium vapour pressure of water at a given temperature. Relative humidity depends on temperature and the pressure of the system of interest. It requires less water vapour to attain high relative humidity at low temperatures; more water vapour is required to attain high relative humidity in warm or hot air.
