Relative Humidity 22
Relative Humidity 22 : The ratio of actual vapour pressure to the saturated vapour pressure at that temperature in the atmosphere. It is commonly expressed as a percentage. It is calculated from the dry bulb (air temperature) and the wet bulb of the whirling hygrometer. It forms one factor of the calculation required to determine whole-body thermal discomfort. Kroemer and Grandjean (1997) recommend that relative humidity in offices in summer should be between 40-60 % and in winter no less than 30%
