Extracted text: Show by dimensional analysis that this leads to the loga rithmic overlap relation (6.28). The following turbulent flow velocity data u(y), for air at 24°C and 1 atm near a smooth flat wall were taken in the University of Rhode Island wind tunnel: Y, mm 0.64 0.89 1.19 1.40 1.65 и, m/s 15.6 16.5 17.3 17.6 18.0 Estimate (a) the wall shear stress and (b) the velocity u at y = 5.6 mm.
