It is a common practice to measure the fluid thrust normal to a solid wall through the small hole which is drilled in the surface of the wall. For viscoelastic flow, however, this experimental technique is not a common practice since some disturbance of the primary flow occures due to the hole, thus yielding in principle an error in measuring the undisturbed pressure. Therefore, there has been much discussion1,2 on this hole pressure error.
