Pressure-Height Graph of a Fluid (Air)

Pressure

Unit
Air pressure (or the pressure of another fluid) at height \(h\) above the sea surface. According to this barometric formula, air pressure decreases exponentially with height.

Pressure at the bottom

Unit
Air pressure at sea level \(h = 0\).

Scale height

Unit
Scale height is a constant that depends, for example, on the temperature of the air and the gravitational acceleration. The scale height is approximately \(H=8\,\mathrm{km}\) on Earth.

Height

Unit
Height measured from the sea surface.
