How to Evaluate Local Skin Friction Coefficient for Turbulent Flow on Flat Plates?

Local Skin Friction Coefficient for Turbulent Flow on Flat Plates evaluator uses Local Friction Coefficient = 0.0592*(Local Reynolds Number^(-1/5)) to evaluate the Local Friction Coefficient, The Local Skin Friction Coefficient for Turbulent Flow on Flat Plates formula is defined as the function of local Reynolds number. In the turbulent core of the boundary layer the eddy viscosity may be as high as 100 times the molecular value experienced in the laminar sublayer, and a similar behavior is experienced for the eddy diffusivity for heat compared to the molecular diffusivity. To account for the Prandtl number effect over the entire boundary layer a weighted average is needed, and it turns out that use of Pr^(2/3) works very well and matches with the laminar heat-transfer–fluid-friction analogy. Local Friction Coefficient is denoted by C_fx symbol.
