Consider moist air with absolute humidity of 0.02 (kg moisture)/(kg dry air) at 1 bar pressure. The vapour pressure of water is given by the equation
ln Psat = 12-4000/(T-40)
where Psat is in bar and T is in K. The molecular weight of water and dry air are 18 kg/kmol and 29 kg/kmol respectively. The dew temperature of the moist air is ______ °C (rounded off to the nearest integer).
