Table 4: represents the variation of the axial pressure gradient pa,z for various values of the Hartmann and Reynolds numbers, for Grashof number Gr=0, and κ=0.2. As the Hartmann number increases the absolute value of the axial pressure gradient highly increases, due to the effect of the opposite direction of the Lorentz force on the direction of the flow.
