Can dew point ever equal wet bulb temperature?

Answer 1

Yes, at saturation.

Answer 2

No, the dew point and wet bulb temperature are two distinct measurements used to describe humidity levels in the atmosphere. The dew point represents the temperature at which air becomes saturated with water vapor, while the wet bulb temperature is the lowest temperature that can be reached through evaporation of water into the air. The two values can be equal only under certain specific conditions that are highly unlikely to occur in nature.
