This method of viscosity measurement involves observing the time it takes for a sphere of known size and density to descend through a stationary fluid of unknown viscosity. The speed of descent is directly related to the viscosity of the fluid. This method is based on the principles of Stokes' Law, which predicts the sphere's settling velocity. == Principle =..."
