Question: 4 when a cylindrical piston moves up and down in...

Question details

4. When a cylindrical piston moves up and down in its chamber, a thin layer of lubricant between the piston and the wall moves along, as shown in Fig. 4. Assume that the process is at steady state. Consider just the upward stroke where the inner piston is being pulled up with a velocity U and the region of interest is of length h Piston Region of interest Figure 4: Piston and cylinder Show that the velocity profile is: Hence, obtain an expression for the shear stress Rin(1-h/R) 2
