Question

How much kilogram of water vapour is contained in a cubic room of length = 4m, if RH = 50%, Temperature = 27°C? (Vapour pressure of water at 27°C is 26.7 torr, RH = Partial Pressure of H2O / Aq tension of H2O)

Answer 1

Answer:

Relative humidity as the ratio of vapor partial pressure in the air - to the saturation vapor partial pressure if the air at the actual dry bulb temperature. pws = saturation vapor partial pressure at the actual dry bulb temperature [mbar].

...

Temperature Saturation Vapor Pressure [10-3 bar]

[oC] [oF]

52 125 134.2

Answer 2

Answer:

% relative humidity = partial pressure of water ×(

)

⟹80= partial pressure of water ×(

)

Hence, the partial pressure of water is 21.6 mm.
