Steady state temperature reached by a small amount of liquid evaporating into a large amount of unsaturated vapour-gas mixture is called the ________________ temperature?
Correct answer: B. Wet-bulb
- A. Dry-bulb
- B. Wet-bulb
- C. Dew point
- D. Adiabatic saturation
Explanation
When liquid evaporates into a large unsaturated gas stream, the liquid cools until evaporation and sensible heat transfer reach equilibrium; this temperature is the wet-bulb temperature. Dew point instead refers to cooling the gas until condensation begins.
