Viscosity and Laminar Flow; Poiseuille’s Law Physics

WebThe flow rate is based on a net force calculation, where it is assumed the only relevant forces are externally applied pressure and viscous forces. Poiseuille's law can be derived using the basic definitions of a pressure-induced force and viscosity. Blood flow in arteries follows Poiseuille’s law 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… bird fountains waterfallsWebAug 28, 2024 · The first is dynamic viscosity, also known as absolute viscosity, which measures a fluid’s resistance to flow.
