Consider incompressible flow at a volume rate Q toward a drain at the vertex of a 45 wedge of width b, as in Fig. P4.33. Neglect gravity and friction and assume purely radial inflow. (a) Find an expression for u,(r). (b) Show that the viscous term in the r-momentum equation is zero. (c) Find the pressure distribution p(r) if p = po at r = R. P4.33 Drain 0 0=/4
