Total skin-friction drag on a plate refers to the cumulative aerodynamic drag force that arises due to the frictional resistance between the fluid flow and the surface of the plate. This drag force results from the shear stresses between the moving fluid layers and the plate’s surface and contributes to the overall resistance encountered by the plate as it moves through the fluid.Â
