A fixed mass of air has a volume of 2.2 m3 and a pressure of 98 kPa. The dry-bulb temperature and degree of saturation of the air are 28°C and 55% respectively. Calculate (i) the relative humidity, (ii) the partial pressure of dry air, (iii) the partial pressure of water vapor, (iv) the mass of dry air, and (v) the mass of water vapor. Show how the state of the air is located on a psychrometric chart.
