Using the available references determine the dew point when the dry bulb temperature is 74°F (23°C) and the wet bulb temperature is 60°F (16°C).

Correct Answer: Option D — 50°F

Using psychrometric tables, the dew point is found by tracking the wet bulb depression. With a dry bulb of 74 degrees Fahrenheit and wet bulb of 60 degrees Fahrenheit, the corresponding dew point temperature is 50 degrees Fahrenheit.
