Versuch: Surface tension by the ring method (Du Nouy method)
Principle: The force is measured on a ring shortly before a liquid film tears using a torsion meter. The surface tension is calculated from the diameter of the ring and the tear-off force.…

Versuch: Viscosity measurements with the falling ball viscometer
Principle: Due to internal friction among their particles, liquids and gases have different viscosities. The viscosity, a function of the substance's structure and its temperature, can be experimental…

Versuch: Viscosity of Newtonian and non-Newtonian liquids (rotary viscometer)
Principle: The viscosity of liquids can be determined with a rotation viscometer, in which a motor with variable rotation speed drives a cylinder immersed in the liquid to be investigated with a spira…
