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 data with a dry bulb of 74°F and wet bulb of 60°F yields a depression of 14°F, locating a corresponding dew point of 50°F, critical for determining safe ventilation parameters for moisture-sensitive cargoes.
