A study of the effect of stratified viscous fluid on MHD free convection flow past a vertical porous plate with heat and mass transfer taking viscous and Darcy resistance terms into account and the constant permeability of the medium numerically and neglecting induced magnetic field in comparison to applied magnetic field is investigated. The velocity, temperature and concentration distributions are derived and discussed numerically with the helps of graphs and tables. It is observed that velocity increases with the increase in Gr (Grashof number), K (Permeability parameter) and b (Stratification parameter), but it decreases with the increase in M (Magnetic parameter).
