The lowest temperature to which water can theoretically be cooled in an evaporative cooling tower is the:
- Dry-bulb temperature of the entering air
- Wet-bulb temperature of the entering air
- Dew-point temperature of the entering air
- Freezing point of water
Answer
B. Wet-bulb temperature of the entering air
Solution
Evaporative cooling can approach, but not go below, the entering air's wet-bulb temperature.
