WebMar 5, 2024 · The viscosity is this the fluid property that characterizes the resistance of the fluid to deformation. For fluids like air and water, the viscosity is indeed an intrinsic property of the fluid, in that it does not depend on the state of motion but only on the nature of the fluid itself. Different fluids have different viscosities. WebWhere is the intrinsic viscosity , is Molecular weight, and are constants for a particular polymer solvent system.

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 the internal frictional force between adjacent layers of fluid that are in relative motion. For instance, when a viscous fluid is forced through a tube, it flows more quickly near th… WebIntrinsic Viscosity. Introduction.
