Abstract
The article gives the results of an experimental investigation of the velocity structure and the hydraulic resistances in not fully developed pressurized turbulent flows in a smooth channel. It gives a description of the experimental unit and of the method used to investigate the kinematic structure and the resistance with not fully developed motion. The distribution of the averaged velocity, of the longitudinal and vertical pulsation velocities, and of the turbulent friction was obtained, and the value of the hydraulic resistance was measured with accelerated and retarded motion. On the basis of the investigations carried out, empirical dependences were obtained to describe the kinematic characteristics and the resistances with not fully developed turbulent motion in a smooth channel.
