1. (relative humidity) The partial pressure of water vapor in air is usually less than the equilibrium vapor pressure (or saturation pressure) at the ambient temperature; this is why a cup of water will spontaneously evaporate. The ratio of the partial pressure of water vapor to the equilibrium vapor pressure (at the same temperature) is called the relative humidity. Saturated air, at 100% relative humidity, would be in equilibrium with a cup of liquid water. The saturation pressure depends strongly...

Air is at 1 atm, 40°C, and 20 percent relative humidity. Water
at 22°C is evaporated into this air to produce air at 25°C and 80
percent relative humidity. How much water, in kg H2O/kg dry air, is
required and how much cooling, in kJ/kg dry air, has been produced?
Use data from the tables.
