Q1: Which of the following parameters remains almost constant during adiabatic saturation of unsaturated air ?A Dry bulb temperature
B Dew point
C Wet bulb temperature
D None of these
ANS:C - Wet bulb temperature During adiabatic saturation of unsaturated air, the process occurs without any heat transfer (adiabatic) as water is added to the air until it becomes saturated. In this process, the wet bulb temperature remains almost constant. The wet bulb temperature is a measure of the lowest temperature that can be reached by evaporating water into the air at constant pressure. During adiabatic saturation, as water evaporates into the air, it cools the air to its wet bulb temperature. Once the air becomes saturated, further addition of water does not change the wet bulb temperature significantly. So, among the options provided, the correct answer is:
