WebFinal answer. (d) Using the Table below, suppose that the air temperature is 20∘C(68∘F) and the relative humidity is 50% at 6:00 PM, and that during the evening the air temperature drops but its water vapor content remains unchanged. If the air temperature drops 1∘C(1.8∘F) every two hours, will you expect a fog to form by sunrise at 6: ... WebHumidification. The psychrometric chart (Figure 108-2) is a tool for understanding the relationships between the various parameters of supply air and the relative humidity. This template allows a designer or operator to “work backwards” from a desired room relative humidity to the desired condition of the air as it enters the supply duct.
