In 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 pressure is the surface integral of the pressure vector field across the surface of the body. The resultant force and center of pressure location produce an equivalent force and moment on the body as the original pressure field. WebMar 3, 2024 · Concept: The point at which the total pressure is suppose to be act is called as center of pressure. It is denoted by h and it is given as, 𝛉 h = x ¯ + I G A x ¯ × sin 2 θ. where, … WebIn providing solutions to this type of engineering problem, the parameters of interest are usually the resultant force and the centre of pressure. 2.
