text: A valid application of Equation (3.42) for calculating the bulk viscosity of a particular liquid requires that this bulk viscosity is independent of the ultrasound frequency, since this independence is assumed in the derivation of Equation (3.40) from the Navier-Stokes equation (Equation 3.35).
