The equation is based on a mathematical analysis using the experimental turbulent flow data in a smooth circular pipe as a reference. The general shear stress equation presented here was tested by solving the momentum equation for several surfaces, including a circular pipe, rectangular ducts, flat plates with and without suction, a very long cylinder perpendicular to the stream, and supersonic turbulent flow over a flat plate and along a circular cylinder. It showed good compatibility with the experimental data.
