Psychrometrics terminology: DBT–WBT difference. What is the name of the difference between the dry-bulb temperature (DBT) and the wet-bulb temperature (WBT) of air? Choose the correct term.

Q: Psychrometrics terminology: DBT–WBT difference. What is the name of the difference between the dry-bulb temperature (DBT) and the wet-bulb temperature (WBT) of air? Choose the correct term.

Definitions Wet-bulb depression = DBT − WBT.Dew point depression = DBT − DPT. Result Therefore, the correct term for (DBT − WBT) is wet bulb depression.

Difficulty: Easy

dry bulb depression
wet bulb depression
dew point depression
degree of saturation

Correct Answer: wet bulb depression

Explanation:

Definitions
Wet-bulb depression = DBT − WBT.Dew point depression = DBT − DPT.

Result
Therefore, the correct term for (DBT − WBT) is wet bulb depression.
