Kekentalan
caption: Laminar shear of fluid between two plates. Friction between the fluid and the moving boundaries causes the fluid to shear. The force required for this action is a measure of the fluid's viscosity. This type of flow is known as a Couette flow .
caption: Laminar shear, the non-constant gradient, is a result of the geometry the fluid is flowing through (e.g. a pipe).
