WebRelative humidity is a term commonly used to describe how much water vapor is in the air as a percent. Saturated air is at 100% relative humidity (RH). Air with a 50% RH and 100°F contains half the water vapor of saturated air at 100% RH and 100°F. Enthalpy describes the heat energy content (BTU/lb dry air) of the air and water vapor mixture. WebRelative humidity (RH) (expressed as a percent) also measures water vapor, but RELATIVE to the temperature of the air. In other words, it is a measure of the actual amount of water vapor in the air compared to the total amount of vapor that can exist in the air at its current temperature.
