Which of the following increases during evaporative cooling process with recirculated water supply ?
Correct answer: A. Both B. and C.
- A. Both B. and C.
- B. Relative humidity
- C. Partial pressure of vapour
- D. Wet bulb temperature
Explanation
Evaporation adds water vapour to the circulating air, increasing both its relative humidity and water-vapour partial pressure. The wet-bulb temperature is approximately constant in ideal adiabatic evaporative cooling, so it is not the intended choice.
