For liquids, it corresponds to the informal concept of "thickness": for example, syrup has a higher viscosity than water. Viscosity quantifies the internal frictional force between adjacent layers of fluid that are in relative motion. For … See more The word "viscosity" is derived from the Latin viscum ("mistletoe"). Viscum also referred to a viscous glue derived from mistletoe berries. See more Transport theory provides an alternative interpretation of viscosity in terms of momentum transport: viscosity is the material property … See more Newton's law of viscosity is not a fundamental law of nature, but rather a constitutive equation (like Hooke's law, Fick's law, … See more Viscosity is measured with various types of viscometers and rheometers. A rheometer is used for fluids that cannot be defined by a single value of viscosity and therefore require … See more Dynamic viscosity In materials science and engineering, one is often interested in understanding the forces or stresses involved in the deformation of … See more The viscous forces that arise during fluid flow are distinct from the elastic forces that occur in a solid in response to shear, compression, or extension stresses. While in the latter the stress is proportional to the amount of shear deformation, in a fluid it is proportional to … See more The SI unit of dynamic viscosity is the newton-second per square meter (N·s/m ), also frequently expressed in the equivalent forms See more WebThe viscosity of dilute and concetrated polymer solutions has been studied for many decades and has played an important role in understanding the effect of ...
