Poiseuille's problem + Navier-Stokes equation PT01

In this video, we derive and explain Poiseuille’s flow starting directly from the Navier–Stokes equations. We show how, under appropriate assumptions (steady, incompressible, fully developed laminar flow), the Navier–Stokes equations reduce to a simple ordinary differential equation that leads to the famous parabolic velocity profile. The physical assumptions behind Poiseuille flow Step-by-step simplification of the Navier–Stokes equations Derivation of the velocity profile Expression of the pressure gradient Wall shear stress and its physical meaning Flow rate and volumetric discharge Reynolds number and laminar flow condition This problem is fundamental in fluid mechanics and appears frequently in engineering, physics, and applied mathematics courses. #fluidmechanicsandhydraulicmachines #NavierStokes #Poiseuille #laminarflow #hydrodynamics #ContinuumMechanics #engineeringstudents #physicslecture #reynolds #shearstress #PressureGradient #appliedmathematics
