_____________ temperature is the steady state temperature attained by a small amount of liquid evaporating into a large quantity of unsaturated gas-vapor mixture ?
Correct answer: B. Wet bulb
- A. Dry bulb
- B. Wet bulb
- C. Dew point
- D. None of these
Explanation
Wet-bulb temperature is reached when a small liquid sample evaporates into a large stream of unsaturated gas and the latent heat removed is balanced by sensible heat supplied from the gas. Dry-bulb temperature is the ordinary gas temperature, while dew point concerns condensation.
