Trouton viscosity
In general, viscosity depends on a fluid's state, such as its temperature, pressure, and rate of deformation. However, the dependence on some of these properties is negligible in certain cases. For example, the viscosity of a Newtonian fluid does not vary significantly with the rate of deformation. See more The viscosity of a fluid is a measure of its resistance to deformation at a given rate. For liquids, it corresponds to the informal concept of "thickness": for example, syrup has a higher viscosity than water. Viscosity quantifies … See more Dynamic viscosity In materials science and engineering, one is often interested in understanding the forces or stresses involved in the deformation of a material. For instance, if the material were a simple spring, the answer would be … 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, and Ohm's law) which serves to define the viscosity $${\displaystyle \mu }$$. Its form is motivated by experiments which show that for … 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 … 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 which characterizes momentum transport within a fluid, just as thermal conductivity characterizes heat transport, and (mass) 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 … See more WebЗунгааралт (англи: viscosity) нь "viscum" гэдэг Латин үгнээс гаралтай бөгөөд энэ нь цагаан борц буюу "mistletoe" ургамалын нэр ба шувууг барьж авахад зориулсан уг ургамлаас гаргаж авсан цавууг ийнхүү ...
