Little is known of the transition of the laminar motion of an oscillating fluid into turbulent motion and the resistance to motion in this region. The theoretical calculation of the critical value of the Reynolds number is very complex in this case and has not yet been successfully accomplished [1, 2]. Some experimental data on this subject are presented in [3]. Below are presented results of measurements of the critical values of the Reynolds number and the resistance forces for laminar and turbulent regimes of fluid oscillations in pipes.
