Anewtonian fluid flows under laminar conditions through a gap between two vertical parallel plates. the flow is steady, one-dimensional and fully developed 2 (a) draw the flow geometry and the control volume at an appropriate location and show clearly all the forces acting on it. [4 marks] derive an equation for the velocity distribution across the gap in terms of the (b) piezometric pressure, the distance between the plates (b), the perpendicular distance measured from the centreline (y), and appropriate physical properties of [13 marks] the fluid. [3 marks] (c) sketch the velocity and shear stress profiles across the gap
