Law of hagen poiseuille
WebPoiseuille's law also applies to many general situations, although it is normally discussed in the context of hemodynamics. Flow in a capillary tube follows Poiseuille’s law equation. … WebThe above expression shows that the Bejan number in the Hagen–Poiseuille flow is indeed a dimensionless group, not recognized previously. The Bhattacharjee and Grosshandler formulation of the Bejan number has large importance on fluid dynamics in the case of the fluid flow over a horizontal plane [8] because it is directly related to fluid …
