Dew Point
The dew point is the temperature at which the air is saturated with
water vapour. Condensation occurs below this temperature. The
dew point generally lies below the air tem perature, except with 100
% r.h, where both temperatures are the same.
The dew point is dependent on the air temperature and water
vapour partial pressure and equal to the temperature whose
saturation pressure is equal to the water vapour partial pressure
present. The water vapour partial pressure is calculated as follows:
