To improve Pohlhausen's method of approximate solution of the laminar boundary layer problem, the velocity distribution in the boundary layer is expressed as follows : u/(u_0)=F(y/δ)+λ'/αG(αy/δ). And the separation point is determined applying the results of exact solutions by Howarth and Tani in the case of flow u_0=U_1-U_nx^n. The separation of turbulent boundary layer was, hitherto, estimated by Buri's parameter [numerical formula]. The relation between T and u_0u_0''/u_0'^2 at the separation point which is obtained by experiment is also shown in the paper.
