The universal velocity profile equation for turbulent flow is obtained for the power law approximation equation. The profile equation should be valid from wall to the center line, from laminar to turbulent flow, and for Newtonian and non‐Newtonian power law materials. The equation is compared with other theoretical and experimental results. In the center line region, where the other theoretical development is valid, both equations give essentially the same results. The experimental confirmation with literature data is good over the entire flow regime.
