Minimum temperature upto which water can be theoretically cooled down in the cooling tower by evaporative cooling is equal to the ______________ temperature of air?
Correct answer: C. Wet bulb
- A. Saturation
- B. Dry bulb
- C. Wet bulb
- D. Dew point
Explanation
In an ideal evaporative cooling tower, water can theoretically approach the entering air's wet-bulb temperature. It cannot cool to the dry-bulb temperature unless there is no humidity effect, and the actual tower outlet remains above wet-bulb temperature.
