Pressure coefficient for incompressible flow calculator

The coefficient of pressure (Cp) is a dimensionless quantity used in fluid dynamics and aerodynamics to describe the pressure distribution around an object, typically an airfoil or an aerodynamic body. It provides a normalized representation of the pressure at different points on the surface of the object with respect to the free-stream or ambient pressure. 

  • Cp is the coefficient of pressure at a specific point on the object’s surface.
  • V is the local velocity of the fluid at that point.
  • V∞ is the free-stream or ambient velocity of the fluid far away from the object.
