Force per unit span acting on the bottom surface of the wedge Calculator

The “force per unit span acting on the bottom surface of the wedge,” denoted as F3′, refers to the aerodynamic force experienced by a unit length of the lower surface of a wedge-shaped object due to fluid flow interactions. This force is primarily a result of the pressure distribution and shear forces on the bottom surface of the wedge as the fluid flows over it. 

• Pressure at the bottom surface of the wedge (p3) in N/m^2
• Length of the face of the wedge (l) in m
• Force per unit span (F3′) in N/m
