Abstract
In the paper, formulas were obtained for calculating a number of quantities characterizing the distribution of the kinetic energy of turbulent fluctuations over the pipe section depending on the Reynolds criterion. Those quantities include the maximum value of the kinetic energy, the average value, the value on the axis. The formulas were constructed using direct numerical simulation data obtained by various authors
