Saturated Air-Water Vapor Mixture

Wet-bulb depression is the term for the temperature differential between the dry bulb and the wet bulb (wbd). The wet-bulb depression for saturated air vapor is zero, meaning that the dry-bulb temperature equals the wet-bulb temperature.

Dew point temperature (dpt): The dew point temperature is the temperature at which condensation begins. Dew point depression is the term for the difference between dry-bulb temperature and dew point temperature (dpd). The dew point depression for saturated air vapor is zero, meaning that the dew point temperature equals the dry bulb temperature.

Summary:

In a saturated air-water vapor mixture, the - (a)Dry bulb temperature is higher than the wet bulb temperature (b)Dew point temperature is lower than the wet bulb temperature (c)Dry bulb, wet bulb, and dew point temperature are the same (d)Dry bulb temperature is higher than the dew point temperature

Dry bulb, wet bulb, and dew point temperatures are all the same in a saturated mixture of air and water vapor. Dry bulb, wet bulb, and dew point temperatures are all the same in a saturated mixture of air and water vapor.
