Unformatted text preview: drop in the flow direction, which is the x-direction (vertically downwards). a) Apply the linear momentum balance for a differential volume and obtain an expression for the shear stress distribution between the plates. b) What is the maximum value of the shear stress and where does it occur. c) If the fluid is Newtonian arrive at an expression for the velocity profile. d) Derive an expression for the volumetric flow rate for a unit width w (into the z direction) of the film and calculate the flow rate per unit width if the fluid is water at room temperature and 2b= 2 mm....
