Q.1 The dry-bulb and wet-bulb temperature of the outdoor air is 33°C and 28°C respectively, and the atmospheric pressure is 101.325 kPa. Without using a psychrometric chart, calculate: the moisture content; (i) (ii) (iii) the relative humidity; the specific enthalpy; (iv) the dew point temperature; and (v) the specific volume of the outdoor air. Given: specific heat of dry air, Cpd = 1.005 kJ/kg-K specific heat of water vapour, Cps = 1.88 kJ/kg-K - latent heat of vaporization at 0°C, híg,0 = 2501 kJ/kg gas constant of dry air, Ra = 287.1 J/kg-K water properties table in Appendix 1. - - (12 marks) (2 marks) (5 marks) (2 marks) (4 marks) Q.1 The dry-bulb and wet-bulb temperature of the outdoor air is 33°C and 28°C respectively, and the atmospheric pressure is 101.325 kPa.
