ii) Dew point temperature. c) Atmospheric air at a dry bulb temperature of 16ºC and 25% relative humidity passes through a furnace and then through a humidifier, in such a way that the final dry bulb temperature is 30ºC and 50% relative humidity. Find the heat and moisture added to the air. Also determine sensible heat factor of the process. OR 8
