DrRoc on Instagram: "Hagen–Poiseuille equation 19th century French physician Poiseuille described how flow is related to perfusion pressure, radius, length, and viscosity. WebA simplified form of the vorticity equation is derived for arbitrary coordinate systems. The present work unifies and extends the previous finding that while vorticity is conserved in planar Euler flow, in axisymmetric Euler rings it is the ratio of the vorticity to the distance from the symmetry axis that is conserved. The unifying
