Velocity at a point Calculator

Velocity (V) at a specific point on an aerodynamic body or airfoil refers to the magnitude and direction of the fluid flow’s speed at that particular location on the surface of the body. In fluid dynamics, velocity is a vector quantity, meaning it has both magnitude (speed) and direction. At any given point on an airfoil or aerodynamic body, the velocity vector represents how fast the fluid is moving and the direction in which it is moving relative to the body.  

• V is the velocity at the specific point on the aerodynamic body (measured in m/s).
• V∞ is the free-stream velocity of the fluid far away from the body (measured in m/s).
• Cp is the coefficient of pressure at that specific point on the aerodynamic body (dimensionless).
