Adiabatic Humidification

In adiabatic humidification, liquid water is sprayed into a relatively dry, warm air stream in a tower. Because some water evaporates, the temperature of the air stream decreases and its moisture content increases. The adiabatic spray tower operates at 1 atm and that the mass flow rate of the stream of air is 1000 kg/hr. You can set the temperature and relative humidity of the inlet air stream. This simulation computes how much water must evaporate (shown in magenta and expressed in kg/h) for a selected relative humidity of the humidified air (i.e. the outlet air stream, shown in red). The rise in water temperature in the tower is much smaller than the heat of vaporization of water. Thus, you can follow the constant wet-bulb line on the psychrometric chart.
