A mixture of air and water vapour at 1.013 bar and 16oC has a dew point of 5oC. Determine the relative and
specific humidities.
Atmospheric air at a pressure of 760 mm Hg has a temperature of 32oC and a percentage saturation as
determined from a psychrometric chart of 52%. Calculate
(i) The partial pressure of the vapour and the dry air
(ii) The specific humidity
(iii) The dew point
(iv) The density of the mixture.
