(Such as a pressure difference between the two ends of the tube.) is need to sustain the flow. It flows more quickly near the tube’s axis than near its walls. For instance, when a viscous fluid is force through a tube. Viscous quantifies the internal frictional force between adjacent layers of fluid that are in relative motion. For example, syrup has a higher viscosity than water. For liquids, it corresponds to the informal concept of “thickness”. The viscosity Gauge is use to measure the fluid of its resistance to deformation at a given rate.
