The conditional analysis of the instantaneous wall friction is applied on time records made in transitional boundary layers originating on smooth surface or surface covered by sand paper (grits 60) under turbulent free stream. The applied intermittency analysis of measurement allowed the evaluations of turbulent and non-turbulent zone averages.
