A viscous fluid (Newtonian) formed by two parallel walls at 2D distance from each other. flows in a laminar flow through a slit. The numerical value of B is much smaller than the numerical value of W (BW), the end effects are not significant. Considering the shape, whether a differential by establishing momentum equivalence, either using the equations of exchange and momentum flux and velocity Obtain the given relations for their distributions. In addition, the average velocity in the slit increases to the greatest velocity. obtain the ratio and the analogy of Hagen-Poiseuille's law for flow
