Reynolds experiment is used to study flow behavior of fluids by slowly and steadily injecting dye into a pipe. The state of fluid flow will be determined and compared with the results from the calculation of the Reynolds number.  (i) Discuss observations made in the Reynolds number.  (ii) Analyze various factors which effect the flow of fluids.

3 A constant-density Newtonian fluid is flowing as a thin film down a vertical wall in laminar flow; see Fig. 15.9. a. Find the velocity distribution and the volumetric flow rate per unit width of wall by using the Navier-Stokes equations (z component) on the assumptions that there is no flow in the x or y direction, that the z component of the velocity is zero at the solid wall, and that there is no shear stress at the liquid-air surface, and the flow is steady-state. (Waves may appear on the fluid surface in this situation; ignore that possibility for this problem). Solid wall * Air Thin liquid film Thickness Ax FIGURE 15.9 A thin liquid film flowing down a wall. b. Repeat the solution to Prob. 3a, showing both the velocity distribution and the volumetric flow rate, for the case in which the flow under the influence of gravity is between two parallel vertical plates, separated by the distance Ax. In Prob. 15.9 the pressure gradient in the flow direction was zero, because the film was…
