In this paper the unsteady flow of viscous incompressible fluid through a uniform pipe of circular cross-section with permeable wall has been studied and the complete solutions for the two velocity distribution have been obtained enclosed form. The axial velocity has been produced and the time dependent linear pressure gradient and the radial outward velocity has been imposed by the porosity on the wall for any value of the section parameter . It has been found out that the axial velocity is maximum along the axis of the pipe and the velocity profiles are symmetrical about the axis of maximum velocity. The result for velocity distribution has been obtained with suction.

Viscous incompressible fluid porous wall outward normal, impermeable wall Hagen-Poiseuille flow.
