Flat plate skin friction coefficient
WebThe skin friction coefficient depends on the Reynolds number of the flow and the roughness of the plate surface. For a smooth flat plate, the skin friction coefficient can be approximated by the Blasius solution for laminar flow and the von Karman solution for turbulent flow. For this problem, we will assume that the flow is turbulent, and use ...
