What is Saturation and Dew point ?


When relative humidity of air becomes 100%. The air is said to be saturated and the temperature at which this occurs is called the due point temperature.

Relative humidity is the percentage ratio of the actual water vapour contained in the given sample to the maximum quantity of water vapour that the sample can hold at that temperature.

RH% = Present quantity of water vapour / Max possible at that temperature * 100
