Dew point temperature of air at one atmospheric pressure (1.013 bar) is 18 deg.c. The air dry bulb temperature is 30deg.c. The saturation pressure of water at 18 and 30 deg.c are 0.02062 bar and 0.04241 bar respectively. The specific heat of air and water vapour respectively are 1.005 and 1.00 kJ/kg K and the latent heat of vapourization of water at 0 deg.c is 2500 kJ/kg. (A) The specific humidity (kJ/kg of dry air) 0.01051 (B) Enthalpy (kJ/kg of dry air) of this moist air respectively 52.64 (C) The specific humidity (kJ/kg of dry air) 0.01291 (D) Enthalpy (kJ/kg of dry air) of this moist air respectively 63.15
