The term viscosity describes the flow behavior of fluid systems. By moving two fluid layers against each other the fluid movements create a resistance (stiffness and internal friction), referred to as flow resistance. Viscous forces are created by moving several layers of fluid at different velocities. This causes faster flowing layers to slow down and slower flowing layers to speed up. These processes follow the laws of physics and can be defined in equations whereby shear rate (velocity gradient) and shear modulus are factors. Viscosities are always dependent on temperature. For example, viscosity measurements are performed to optimize a paste-like substance with regard to consistency or to optimally adjust it for the production line.
