The Navier-Stokes equations in cylindrical coordinates reduced to fourth order non-linear ordinary differential equation, con taining a parameter Rew, the wall Reynolds number. The semi-analytical solution of the set of governing equations with suitable slip flow boundary conditions is presented by using power series method to obtain velocity profile, pressure gradi ent and friction coefficient. Also the effect of slip coefficient on velocity profiles and pressure gradient is studied and their graphical solutions are also providedenDr. Muhammad Younassp15Department of MathematicsMathematicsPorous SurfaceTube Flow SystemThesis
