The flow of an incompressible viscous fluid in a porous pipe has been considered by many investigators. but these studies have been performed under the assumption that the wall suction or the injection velocity are constant to the axis. It is natural that the filtration or the absorption velocity across the wall depends on the difference the hydorostatic pressure between the inner and outer wall (Starling's hypothesis). But analysis based on Starling's hypothesis has been difficult to calculate because of the feedback condition which causes numerical instability. In the present paper, this problem is improved by the penalty function method. We show here that flow in a porous pipe is controlled by the porosity or the pressure difference across the porous wall.
