A Note on the Unstaedy Flow of a Visco-Elastic Maxwell Fluid Through a Rectilinear Pipe

The unsteady ow of a visco-elastic Maxwell uid through a rectilinear pipe having its cross-section as a parallelogram under the in uence of a axial pressure gradient (I) varying linearly with time , and (II) decreasing exponentially with time has been discussed in the present paper. Variables separable and Laplace transform methods have been used to solve the problem.
