Stokes' dream: Measurement of fluid viscosity from the attenuation of capillary waves
American Journal of Physics
The determination of viscosity from the attenuation of capillary waves was first suggested by Stokes more than a century ago. At the time, it was not practical to measure the attenuation of surface waves with the requisite precision to render the method useful. We describe a noncontact method for measuring the wavelength and amplitude of single-frequency capillary waves to obtain reliable values of the surface tension and viscosity. The attenuation data for several glycerin-water mixtures are used to obtain the viscosity as a function of glycerin concentration. For a wide range of viscosity, the method yields results that are in good agreement with the most reliable published data. © 2010 American Association of Physics Teachers.
