UDC 532.5

Consideration is given to the problem of the proper 
motion of a rotary fluid that fills the entire cylindrical tank in 
the presence of outflow through a rigid bottom. The problem is solved 
in a quasistatio-nary formulation within the framework of the ideal-fluid 
model with allowance for hydraulic losses in the flow of the fluid 
through the bottom of the vessel. The spectrum of eigenvalues is investigated 
and the characteristics of wave motions of the fluid are revealed; 
the results of calculating the wave numbers and the complex attenuation 
factor are given.
