Q. The humidity of air at a dry-bulb temperature of 65 oC is 0.025 kg water/kg dry air. The latent heat of vaporization of water at 0 oC is 2500 kJ/kg. The psychrometric ratio of air is 0.95 kJ (kg dry air)-1 K-1. Considering 0 oC as reference temperature, the enthalpy of air (in kJ/kg) at its adiabatic saturation temperature of 35 oC is
Ans: 124 to 125
