The fully developed steady laminar flow of a generalized second grade fluid of a power-law type through a narrow space between two fixed surfaces of revolution, having a common axis of symmetry, is considered. One obtained the solution of this problem using the boundary layer equations expressed for axially symmetric case in a curvilinear orthogonal coordinate system connected with one of the surfaces. The method of averaging inertia and viscoelastic terms is used to find the formula expressing the pressure distribution in a clearance between fixed surfaces of revolution.
