An Exact Solution to the Draining Reservoir Problem of the Incompressible and Non-Viscous Liquid
Hong, Seok-In
European Journal of Physics, v30 n2 p277-283 Mar 2009
The exact expressions for the drain time and the height, velocity and acceleration of the free surface are found for the draining reservoir problem of the incompressible and non-viscous liquid. Contrary to the conventional approximate results, they correctly describe the initial time dependence of the liquid velocity and acceleration. Torricelli's law does not hold in the initial transient region, which imposes restrictions on the validity of the analogy between the drain system and the electric circuit (Ohm's law).
