A Newtonian fluid is confined between two parallel, vertical and stationary plates of width W, separated at distance H as shown in Figure Q3. III. W x L Figure Q3 At a far enough distance down the wall, the flow is fully developed, is laminar, and its velocity profile, v, is given by: 1 dp + pg) (Hx - x2) 2ndy An average velocity is defined by: 1 Vyav IST Dy dzdx Using appropriate boundary conditions, show that the expression for the average velocity of the fluid, y flowing between the plates is given by: H2 har et + ) 124 Vy.av + pg
