The dew point calculation with a dry-bulb of 74°F and a wet-bulb of 74°F results in what dew point and relative humidity?

When the dry-bulb and wet-bulb temperatures are the same, the air is fully saturated with moisture and cannot evaporate more water. That means relative humidity is 100%, and the dew point—the temperature at which air becomes saturated—must be the current air temperature. With a dry-bulb of 74°F and a wet-bulb of 74°F, the air is at 100% relative humidity, and the dew point is 74°F.
