An investigation of acoustic wave propagation in vapour-liquid mixture with momentum transfer is presented. The approximate solution indicates that the total force of interfacial interaction is actually the Stokes viscous drag force only at sufficiently low frequencies. Due to viscosity, at these frequencies it is independent of frequency because velocity perturbations penetrate into the vapour over the characteristic time of oscillation to a distance much greater than the drop let size in a flowing liquid-vapour mixture.
