A sample of moist air with a volume of 3.5m3 has a dry bulb temperature of 40°C and a relative humidity of 50%. The total pressure is 90 kPa. Calculate (i) the humidity ratio, (ii) the degree of saturation, (iii) the specific volume, (iv) the mass, and (v) the enthalpy. Show how the state of the air is located on a psychrometric chart.
