The discussion focuses on understanding the velocity diagram for a rotating blade, specifically the vectors W and V in relation to the tip speed velocity U. W represents the velocity vector relative to the blade, indicating the flow of fluid along the blade surface, while V denotes the velocity vector relative to the ground. The angles alpha and beta, which are not shown in the diagram, are crucial for a complete understanding, with beta likely representing the angle between the blade and the inner hub.
