The “drag on a unit span of the wedge,” often denoted as , refers to the aerodynamic force acting on a unit span (usually 1 meter) of a wedge-shaped object due to the airflow around it. This force is known as drag, and specifically quantifies the drag force per unit span length.
- Drag on a unit span of the wedge (D’) in N/m
- Length of the wedge (l) in m Wedge angle (𝜃) in rad
- Pressure over the base (p2) in N/m^2
- Freestream static pressure (p1) in N/m^2
