Falling Ball Viscometer

The falling ball viscometer system helps the students determine the viscosity of three different liquids (water, glycerin, and oil). Several small spheres of different sizes and densities are timed as they drop through each fluid. The data obtained is then used by the students to determine fluid viscosity. The experiment is done as a team but the pre-lab and post-lab reports are done individually (just for this experiment).
