Center of pressure (fluid mechanics) ... The center of pressure is the point where the total sum of a pressure field acts on a body, causing a force to act through that point. The total force vector acting at the center of pressureis the value of the integrated vectorialpressure field.

The difference between the two is the 'dynamic pressure'. The 'total pressure' is the sum of the static pressure, the dynamic pressure, and the gravitational potential energy per unit volume. It is therefore the sum of the mechanical energy per unit volume in a fluid.
Integrating the pressure times the surface area around the body determines the aerodynamic force on the object. ... There are severalimportant problems to consider when determining the center of pressure for an airfoil. As we change angle of attack, the pressure at every point on the airfoil changes.
