The velocity v (m/s) of air flowing past a flat surface is measured at several distances y(m) away from the surface. Use Newton's viscosity law to determine the shear stress t (N/m2) at the surface (y=0). dv To dy Assume a value of dynamic viscosity u=1.8. 10-N.s/m2 0 0.002 0.006 0.012 0.018 0.024 0 0.287 0.899 1.915 3.048 4.299 y, m V, m/s (=?)
