NEW FORMULAS FOR CALCULATING THE FLUID FLOW CHARACTERISTICS IN A CIRCULAR PIPE

We propose new formulas for calculating the friction factor in pipes with smooth walls and relations between the mean and the maximum fl uid flow velocity in a pipe. The formulas are in better agreement with experimental data than the literature relations. An expression for the friction factor suitable for all fl ow conditions is proposed. The results of this work can be used in calculating the hydraulic resistance of pipes, as well as in calculating the heat and mass transfer processes in apparatuses incorporating tubular elements.
