Which of the following decreases during evaporative cooling process with recirculated water supply ?
Correct answer: A. None of these
- A. None of these
- B. Relative humidity
- C. Partial pressure of vapour
- D. Wet bulb temperature
Explanation
In adiabatic evaporative cooling, some water evaporates, so the air's humidity and water-vapour partial pressure increase while its wet-bulb temperature remains nearly constant. Therefore none of the listed quantities decreases.
