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...
1) An air-water vapor mixture at 95°F has a relative humidity of 45%. Calculate the partial pressure of the water vapor and its dew-point temperature. (Hint: Psychrometric chart is really useful for this.)
