For numerical  simulation of drainage of a liquid from a volume 
of  arbitrary cross section the Navier-Stokes equations for  an 
incompressible liquid are used. Formulation of and an algorithm 
for solution  of the initial-boundary-value problem and results 
of  calculations  of  drainage  from symmetric and nonsymmetric 
volumes are  considered.  Isolines  of  the  Cartesian velocity 
components, distributions  of  the  velocity  vectors,  and the 
position of the free surface for  different moments of time are 
presented. Calculations are performed  within  the framework of 
a package of applied  programs  developed  by  the  author  for 
solving the of Euler and Navier-Stokes equations.
