Determination of Viscosity with the Falling Ball viscometer According to Höppler

When a substance (gas, liquid or solid) deforms, it opposes the change in form by a resistance which is generally referred to as its viscosity. If one liquid layer moves at constant speed in a direction parallel to a second layer, then a force friction acts between the two layers. The friction converts the energy of motion into heat. For this reason, the viscosity of a substance is a measure of the internal friction. The viscosity of a substance determines how well or poorly it flows in a pipe (e.g. blood through a vein) and how much resistance it exerts against a solid body moving in it.
Viscosity is highly temperature dependant. Experiment C3.1.2.1 studies the dependence of the viscosity on concentration in concentrated sugar solutions at room temperature.
