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… http://web.mit.edu/16.unified/www/SPRING/fluids/Spring2008/LectureNotes/f12.pdf iphone 11 black and white cover
