The article presents results of an experimental study on determination of damping coeffi-
cient in a rigid cylindrical tank with a permeable divider between two layers of liquid.
We developed an installation for initiation of symmetric fluctuations of liquid in a tank.
Analytical dependence for determination of damping coefficient on the basis of the exact
analytical solution of the corresponding boundary problem is received for the first time.
Keywords:
ideal liquid, axisymmetric fluctuations, viscous resistance, damping coeffi-
cient.
