The novel method of measuring turbulence intensities and shear stress by a rotating single hot wire anemometer presented by Fujita and Kovasznay [Rev. Sci. Instrum. 39, 1351 (1968)] was used to make turbulence measurements in the wake of a thin flat plate. While measurements of turbulence levels proved as accurate as could be expected, shear stress measurements made by this method were better than inferred from the analysis. Inclusion of higher order terms in it showed the resulting equation to be identical but the assumptions to be less restrictive.
