853. 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).

The dew point is determined by the intersection of the 74F dry bulb and 60F wet bulb lines on a psychrometric chart, which corresponds to 50F. This value satisfies the condition that the dew point must be less than or equal to the wet bulb temperature, which is less than or equal to the dry bulb temperature.
