The vapour pressure of water in at `20^(@)C` is 12mm of Hg on a particular day the sturation vapour pressure of water at `20^(@)C` is `17.5 mm` of Hg Calculate relative humidity .

Text Solution

Verified by Experts

Relative humidity
`=("Vapour pressure of water in air")/("Saturated vapour pressure of water") `
(Both at same T)
` = (12)/(17.5) = 0.69` .
