Blowing into a water manometer is a simple way to determine a person's pulmonary capacity. The pressure in the manometer is , where
is the density of water,
is the gravitational acceleration, and
is the difference of the height of the water in the two columns; adding the atmospheric pressure
, equal to
, gives the total pressure to raise the water column.
