As you climb higher from the surface, the atmospheric pressure decreases. Upon removing the plug, no matter the internal diameter, depth, angle of inclination of the tube, or the height of mercury in the basin, the mercury will sink, oscillate, and finally come to rest at a height of about 30 inches (760 mm) above the level of the mercury in the basin. Atmospheric pressure can be measured with this experiment, first performed in 1643 by Torricelli, a pupil of Galileo. In the first experiment we validate Torricelli’s law, which shows (ignoring viscosity) that the exit speed of a fluid depends only on the height of the column of water above it.
