During dehumidification of unsaturated air wet bulb temperature & partial pressure of vapor are not constant. However, during evaporative cooling process with recirculated water supply, the _________________ remains constant ?
Correct answer: D. Wet bulb temperature
- A. None of these
- B. Partial pressure of water vapor
- C. Relative humidity
- D. Wet bulb temperature
Explanation
With recirculated water, ideal evaporative cooling is approximately adiabatic saturation, so the wet-bulb temperature remains constant. Water-vapour partial pressure and relative humidity change as evaporation proceeds.
