What is viscosity? Ad Precision equipment for all your testing needs Viscosity index - Wikipedia Viscosity index - Wikipedia List of viscosities - Wikipedia Temperature dependence of viscosity - Wikipedia 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 can be conceptualized as quantifying the internal frictional force that arises between adjacent layers of fluid that are in relative motion. For instance when a fluid is forced through a tube it flows more quickly near the tube's axis than near its walls. In such a case experiments show that some stress (such as a pressure difference between the two ends of the tube) is needed to sustain the flow through the tube. This is because a force is required to overcome the friction between the layers of the fluid which are in r… For instance when a fluid is forced through a tube it flows more quickly near the tube's axis than near its walls.
