The temperature of water cooled in cooling tower is always _________________ temperature of entering air?
Correct answer: A. More than the wet bulb
- A. More than the wet bulb
- B. Less than the wet bulb
- C. Equal to the wet bulb
- D. Equal to the dry bulb
Explanation
A cooling tower cannot normally cool water below the entering-air wet-bulb temperature because that temperature represents the evaporative cooling limit. The cooled water temperature therefore remains higher than the wet-bulb temperature, although it may approach it closely.
