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. WebMathematically, the rotation of a fluid element is equal to 1 2 ( ∇ × v) . However, for an irrotational flow field ∇ × v = 0 . As a result, the curl of the velocity is equal to zero. By making this statement, it will allow us to state …
