How to Evaluate Shear Stress at Wall given Friction Coefficient?

Shear Stress at Wall given Friction Coefficient evaluator uses Shear Stress = (Friction Coefficient*Density of Fluid*(Free Stream Velocity^2))/2 to evaluate the Shear Stress, The Shear Stress at Wall given Friction Coefficient formula is defined as the function of friction coefficient, density and free stream velocity. When an external force acts on an object, It undergoes deformation. If the direction of the force is parallel to the plane of the object. The deformation will be along that plane. The stress experienced by the object here is shear stress or tangential stress. It arises when the force vector components which are parallel to the cross-sectional area of the material. In the case of normal/longitudinal stress, The force vectors will be perpendicular to the cross-sectional area on which it acts. Shear Stress is denoted by 𝜏_w symbol.
