Question:

In turbulent flow past a flat surface, the velocity u near the wall varies approximately logarithmically with distance y from the wall and also depends upon viscosity μ, density ρ, and wall shear stress τw. For a certain airflow at 20°C and 1 atm, τw = 0.8 Pa and u = 15 m/s at y = 3.6 mm. Use this information to estimate the velocity u at y = 6 mm.
