Viscosity is an important concept in fluid mechanics. The viscosity of a fluid is a measure of its ability to resist gradual deformation caused by shear stress or tensile stress. Shear resistance in a fluid is caused by intermolecular friction exerted when the layers of the fluid try to slide against each other, and viscosity is a measure of a fluid's resistance to flow. Mainly divided into absolute viscosity and kinematic viscosity. The falling ball viscometer is a device used to explore the viscosity of fluids and factors affecting fluid viscosity. It mainly consists of two parts. One part is the experimental material (metal ball), and the other part is the experimental container. The container is filled with viscous fluid and can allow Heating (requires external heating container). The falling ball viscometer can observe the viscosity of the fluid in real time and explore the factors that affect the viscosity of the fluid.
1.2 Features
