Atmospheric boundary layers are very thick but followformulas very similar to those of flat-plate theory. Considerwind blowing at 10 m/s at a height of 80 m above a smoothbeach. Estimate the wind shear stress, in Pa, on the beach ifthe air is standard sea-level conditions. What will the windvelocity striking your nose be if (a) you are standing up andyour nose is 170 cm off the ground and (b) you are lying onthe beach and your nose is 17 cm off the ground?
