Extracted text: |Umax u = u(r) Is this flow a. Internal or external? b. viscous or inviscid? C. one dimensional or two dimensional? d. Find the correct expression for the velocity field u(r) e. Find the shear stress at each point in the fluid (What coordinate system should you use?) Find numbers for umax and the diameter of the pipe and the viscosity of the fluid for an application that is of interest to you, e.g. for blood vessels or flow in hydraulic pipes and use them for the calculations. f. Find the shear force per unit length of the pipe. g. How much does this shear force decelerate the fluid? Comment on why you think the result makes sense.
