Question

A parcel of air at 25% relative humidity is holding 2 grams H₂0 / kilogram of air. What could the parcel hold if it were completely saturated?

Answer 1

• 8 grams

Given :

• A parcel of air at 25% relative humidity holding 2grams H2O per kg of air

To find :

• Amount the parcel could hold if it were completely saturated

Solution :

• Relative humidity : It's the ratio of the actual amount of vapours of water present in the air to the greatest amout it could hold at the same temperature.

25% relative humidity means the air is saturated to only an extent of 1/4th the actual complete saturation and thus, when fully saturated, it would hold 4 times the more water vapours per kilograms,

• 2gm x 4 = 8grams H20/Kg of air

Thus,when fully saturated,it would hold 8 grams H20/Kg of air.
