Viscometer with falling ball 3D virtual laboratory work on physics (section: Mechanics).
INTENTION: Simulation of the laboratory work on general physics.
PURPOSE: Determination of dynamic viscosity of aqueous glycerin solution.
DESCRIPTION: Dynamic viscosity is a coefficient of proportionality between body momentum and surface tension in a liquid, characterizing how difficult it is for a body to pass through a liquid. It can be measured with a falling ball viscometer like the one developed by Geppler. It is also possible to measure as a function of temperature if a circulating thermostat is also used. An aqueous glycerine solution is used for the measurements in this experiment. This allows the viscosity dependence on temperature to be described using the Andrade equation.
