AIR HUMIDITY
A certain amount of water vapour is always present in the air: the air's capacity
to withhold water vapour increases with its temperature.
For example, at a temperature of 26°C, the maximum humidity content is 21.4
g of water vapour per kg of air, while at 30°C, the maximum humidity content
is 27.2 g of water vapour per kg of air. In actual fact, the maximum humidity
contents constitute extreme cases which do not occur at our latitudes. In these
conditions, air is said to be 'saturated' (i.e. it cannot contain any more humidity)
and the water vapour begins to condense. 'Relative humidity' refers to the ratio
between the air's actual humidity and the maximum possible humidity content
at that particular temperature.
For example, if said temperature were to be 26°C, the actual humidity content
would be 10.7 g of water vapour for each kg of air, and the relative humidity
would be:
10.7 x 100
= 50%
21.4
Relative humidity is always expressed as a percentage value (%). Apart from
natural causes, the air's humidity in enclosed spaces can increase due to the
number of people present, the activities being performed, etc. Both too little
and too much humidity are harmful to the human body, for opposite reasons,
and should thus be avoided.
