2. Some models also employ a valve for closing the cistern, enabling the mercury column to be forced to the top of the column for transport.
3. The mercury column was required because vacuum pumps of the time could not provide the high vacuum needed to operate a carbon emitter for a practical duration.
4. where ? is the density of mercury, g is the gravitational acceleration, and h is the height of the mercury column above the free surface area.
5. It consists of a conventional bulb connected to a capillary in which a constriction is placed so that upon reversal the mercury column breaks off in a reproducible manner.
6. One proposal was to devise a unit based on a mercury column that would be coherent  in effect, adjusting the length to make the resistance one ohm.

8. As it was observed that the pressure was directly proportional to the height of the mercury column ( Hg ), the millimetre of mercury was adopted like measurement of pressure.
9. Barometers do measure absolute pressure by holding a vacuum at the top of the mercury column or one side of a diaphragm, but that vacuum is awkward to achieve and maintain.
