ABSTRACT

In the present paper the flow of an incompressible viscous fluid through a straight circular tube is considered. The innerside of the circular cylindrical tube is coated with porous lining of thickness δ, radious of the tube is taken to be ‘b’ and the clear region (excluding the porous lining) will be of radious ‘a’. The problem becomes the two layered flow one in porous region and other in clear region. This has analogy with blood flow which considered to be two layered. The effect of magnetic field, porous lining on the flow of the fluid is investigated.

**Key words : **Incompressible
