A liquid column of height h is confined in a vertical tube of cross-sectional area A by a stopper. At t = 0, the stopper is suddenly removed, exposing the bottom of the liquid to atmospheric pressure.

Using a control-volume analysis of mass and vertical momentum, derive the differential equation for the downward motion v(t) of the liquid. Assume one-dimensional, incompressible, frictionless flow.
