Unsaturated air (with dry and wet bulb temperatures being 35 and 25°C respectively) is passed through water spray chamber maintained at 35°C. The air will be__________________?
Correct answer: B. Humidified
- A. Cooled
- B. Humidified
- C. Both A. & B.
- D. Dehumidified
Explanation
The spray water is at 35°C, equal to the air dry-bulb temperature, so it does not provide sensible cooling. The unsaturated air absorbs water vapour and is therefore humidified.
