What is Rolling-Ball Viscometer Analysis about?
1. The rolling-ball viscometer uses a sphere rolling down an inclined tube filled with liquid to determine fluid viscosity. The terminal velocity of the ball is related to viscosity. 2. A force balance equating pressure drop across the tube to gravitational and buoyancy forces on the ball yields an equation relating viscosity to ball velocity, tube dimensions, fluid densities, and gravitational acceleration. 3. The drainage of liquid from a surface over time involves an unsteady mass balance that results
