Abstract: | The assumptions leading to the barometric formula are discussed, with remarks on the influence of temperature, gravitational
field, Earth rotation, and non-equilibrium conditions. A generalization of the barometric formula for negative heights, e.g.,
for pressure inside shafts and deep tunnels, is also presented, and some surprising conclusions obtained. Related historical
aspects are also discussed. |
