When a fluid flows over a surface, the shear stress τ (N/m2) at the surface is given by the expression where μ is the viscosity (N-s/m2), u is the velocity parallel to the surface (m/s), and y is the distance normal to the surface (cm). Measurements of the velocity of an air stream flowing above a surface are made with an LDV (laser-Doppler-Velocimeter). The values given below were obtained. At the local temperature, μ = 0.00024 N-s/m2. In four decimal places, calculate du/dy at the surface using all the points.
