2. Accounting basic patterns
According to the research of water-glycerin liquid PGV in the Scientific Research Institute of Physics, St.
Petersburg University, the bulk viscosity at high frequencies is small. At low cyclic frequencies it seeks to its static
limit (Fig. 1, curve 1), since the frequencies of dynamic loads are relatively small and are in the audible range. This
is the bulk viscosity that can be considered estimated. But, when added to a liquid, for example, cyclohexanol (7%
of the mass), the viscosity increases sharply (curve 2) and seeks to viscosity PGV (curve 1).
