![]() ![]() There exist a number of forms of viscosity: Non-Newtonianįluids exhibit a more complicated relationship between shear stress and velocity gradient than simple linearity. It is notĪ fundamental law of nature but an approximation that holds in some materials and fails in others. Newton's law of viscosity, given above, is a constitutive equation (like Hooke's law, Fick's law, Ohm's law). Viscosity, the slope of each line, varies among materials Combining these three relations results in the equation: The applied force is proportional to the area and velocity gradient in the fluid and inversely proportional to theĭistance between the plates. If this forceĮlastically until the shear stress in the substance balances the applied force), the substance is called a fluid. This type of flow is known as a Couette flow.Īpplied to the upper plate. The force required for this action is a measure of Friction between the fluid and the movingīoundaries causes the fluid to shear. ![]() Laminar shear of fluid between two plates. Made from mistletoe berries and used for lime-twigs to catch birds. The word 'viscosity' derives from the Latin word 'viscum alba' for mistletoe. The study of flowing matter is known as rheology, which includes viscosity and related concepts. Stress is known as an ideal fluid or inviscid fluid. Superfluids) have some resistance to stress and therefore are viscous, but a fluid which has no resistance to shear ForĮxample, high-viscosity felsic magma will create a tall, steep stratovolcano, because it cannot flow far before itĬools, while low-viscosity mafic lava will create a wide, shallow-sloped shield volcano. Viscosity describes a fluid's internal resistance to flow and may be thought of as a measure of fluid friction. Put simply, the less viscous the fluid is, the greater Lower viscosity, while honey is 'thick', having a higher viscosity. InĮveryday terms (and for fluids only), viscosity is 'thickness' or 'internal friction'. ![]() Viscosity is a measure of the resistance of a fluid which is being deformed by either shear stress or tensile stress.
