Question

9. (opts) For Newtonian liquid flow past a flat plate (parallel and perpendicular to a plate as in Figure 3.9 a&b on page 64 of text), where is skin friction the largest (explain or indicate on the figure below): form friction the largest (explain or indicate on the figure below)? which direction is the top eddie rotating - clockwise or counter clockwise? write an equation for shear stress that best represents conditions in the eddie and define your parameters Direction of Row Varying velocity Uniform velocity Uniform velocity Eddies b)
