Unformatted text preview: within a distance of the order of 0.1 a from the wall (by what fraction of itself does the stress actually vary in this region?), and that the inertial (logarithmic) sublayer starts at y + = 50. Based on these considerations and the Blasius friction factor correlation, how high do you estimate that the Reynolds number Re=u av (2a)/ ν must be for there to be room for any inertial sublayer at all in the inner region of the flow? Comment....
