WebNov 20, 2015 · This is the case for flow in a pipe. At low flow rates the pressure drop Δ P is related to the flow rate Q by the Hagen-Poiseuille equation: Δ P = 8 μ ℓ π r 4 Q. where ℓ is the pipe length and r is the pipe radius. So in this case the pressure drop is proportional to the viscosity μ. However at high flow rates the pressure drop is ... WebSep 12, 2024 · The precise definition of viscosity is based on laminar, or nonturbulent, flow. Figure shows schematically how laminar and turbulent flow differ. When flow is laminar, layers flow without mixing. When flow is turbulent, the layers mix, and significant velocities occur in directions other than the overall direction of flow. 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… tsw sebring 18 5x108 offset

Flow is proportional to pressure difference and inversely proportional to resistance: Q = P2 − P1 R. For laminar flow in a tube, Poiseuille’s law for resistance states that R = 8ηl πr4. Poiseuille’s law for flow in a tube is Q = (P2 − P1)πr4 8ηl.
