Question
The relative humidity of ambient air at 300 K is 50% with a partial pressure of water vapour equal to Pπ. The saturation pressure of water at 300 K is Pπππ. The correct relation for the air-water mixture is
Options :
Pπ£ = 0.5 Pπ πt
Pπ£ = 0.5 Pπ πt
Pπ£ = 0.622 Pπ πt
Pπ£ = 2 Pπ πt
Answer :
Pπ£ = 0.622 Pπ πt
Solution :
Ο = 0.5,
β΄ Pv = 0.5 Pvs
Or
Pv = 0.5 Psat
