H-6535-7 VISCOSITY DEMONSTRATOR

The Hampden Model H-6535-7 Viscosity Demonstrator provides the student with the means to perform experiments in the measure of viscosity. The application of shear stress to a fluid results in the continual and permanent distortion known as flow. Viscosity is the resistance of a fluid to its internal friction i.e. Shear motion. This resistance is due to cohesion of the molecules and molecular transfer from one layer to another setting up a tangential or shear stress. Cohesion predominates in liquids, as temperatures increase cohesion decreases as does viscosity.
