Which of the following expressions correctly defines relative humidity?
- A. S.V.P at room temp. / S.V.P at dew point x 100%
- B. S.V.P at the temp of atmosphere / Partial pressure of water vapour x 100%
- C. Density of water vapour in the atmosphere / Density of saturated water vapour at same temp. x 100%Correct
- D. Mass of equal volume of saturated water vapour / Mass of water vapour in a given volume of atmosphere x 100%
Explanation
Relative humidity is the ratio of the actual density (or partial pressure) of water vapour present to the density (or pressure) of saturated water vapour at the same temperature, expressed as a percentage.
