Atmospheric air at 100∘F (37.8∘C) dry-bulb and 65∘F (18.3∘C) wet-bulb temperature is humidified adiabatically with steam. The supply steam contains 10% moisture and is at 16 psia (110.3 kPa). What is the dry-bulb temperature of the humidified air if enough steam is added to bring the air to 70% rh?
