Annotation
It is shown that during nonresonant excitation of waves of the capillary and gravitational-capillary frequency ranges on a fluid surface, the threshold amplitude of cophased pumping oscillations depends not only on dissipative (viscous) losses but also on radiation losses of the system. An experimental justification of the suggested method for determining the fluid viscosity is given.
