The cooling effect in a cooling tower cannot be increased by_____________________?
Correct answer: D. None of these
- A. Increasing the air velocity over the wet surfaces
- B. Reducing the humidity of entering air
- C. Lowering the barometric pressure
- D. None of these
Explanation
All three changes can enhance cooling: higher air velocity improves contact, drier entering air increases evaporation potential, and lower pressure promotes evaporation. Therefore, none of options a to c is a factor that cannot increase the cooling effect.
