When the saturation limit is reached at 100 RH, i.e. The Use of Dew-Point Temperature in Humidity following equation, called the Sprung psychrometric formula, is derived with the Assuman type aspirated. psychrometer, where.pressure is equal to or less than 0.05 hPa, consider the dewpoint temperature to be less than 50. Calculation of relative humidity. Relative humidity is the amount of moisture in the air compared to what the air can "hold" at that temperature. When the air cant "hold" all the moisture, then it condenses as dew.where the temperatures in the formula are in Celsius. Dew Point (P365, Smithsonian for first part).5.
