An Introduction to Dynamic vs. Kinematic Viscosity

Webthe fluid is assumed to be isotropic, as with gases and simple liquids, and consequently is an isotropic tensor; furthermore, since the stress tensor is symmetric, by Helmholtz decomposition it can be expressed in terms of … WebFeb 20, 2024 · Viscosity has units of (N / m2) s or Pa ⋅ s. 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. 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. chindrapet
