Detailed explanation-1: -The dew point is the temperature the air needs to be cooled to (at constant pressure) in order to achieve a relative humidity (RH) of 100%. At this point the air cannot hold more water in the gas form.
Detailed explanation-2: -A relative humidity value of 50 percent means the air contains half of the water vapor it could hold at that temperature. The complication is that air’s capacity to contain water vapor increases dramatically as its temperature rises. Thus, relative humidity depends on the air temperature and its moisture content.
Detailed explanation-3: -ple The relative humidity in a closed room at 15°C is 60%.
Detailed explanation-4: -Measure the air temperature T, in °C. Find out the dew point temperature Dp, in °C. Calculate relative humidity RH using the formula, RH = 100 × exp[17.625 × Dp/(243.04 + Dp)]/exp[17.625 × T/(243.04 + T)]. 02-Feb-2023
