When a fluid flows over a surface, the shear stress T (N/m²) at the surface is given by du T = H- dy where u is the viscosity (N-s/m?), u is the velocity parallel to the surface (m/s), du/dy the acceleration (m/s?), and y is the distance normal to the surface (cm). Measure- ments of the viscosity of an air stream flowing above a surface are made with an LDV (laser Doppler velocimeter). The following values were obtained at u = 0.00024 N-s/m?: y 0.0 0.00 1.0 55.56 2.0 88.89 3.0 100.00
