Dew point temperature: the saturation temperature at the partial pressure of the water vapor, i.e.This process is normally simplified into an isoenthalpic transformation. In other words it is the temperature reached by the air if subjected to water humidification up to saturation conditions. Wet bulb temperature: the lowest temperature achievable by evaporating water into air at constant pressure.Enthalpy: the total value of internal energy contained in the mixture.Simplifying it can be seen as the ratio between the water content of the mixture and the maximum content that could be present at the same temperature and pressure Relative Humidity: ratio between vapor pressure and saturated vapor pressure at the same temperature.Absolute humidity: the amount of water vapor contained in the air ].
