✦ Synopsis

This paper deals with the pressure in a steady two-dimensional/axisymmetric MHD/Brinkman flow of an incompressible viscous electrically conducting fluid over a flat stretching sheet. The stretching rate of the two-dimensional case is assumed as double the stretching rate of the axisymmetric case in order to compare them by means of a unified scale. A recently proposed approximate analytic technique Kumaran et al. [1] was used to recover an exact solution of the two-dimensional case and developed an approximate analytical solution of the axisymmetric case by Kumaran and Tamizharasi [2]. In this paper, the pressure distribution of the MHD and the porous medium cases are plotted and compared. In the MHD case, the pressure distribution is finite. Also, the pressure distribution is totally different in the outer boundary layer for the two-dimensional and the axisymmetric cases.
