Bala Yabo Isah, Muhammad Muhammad Altine, Sama'ila Kamba Ahmad.

Abstract
Conclusion

The solution of thermal radiation and variable pressure effects of a viscous,incompressible and electrically conducting fluid
between vertical porous medium is gained. In the absence of mass transfer equation [3] and Gr = N =M = K = Sc = δ, our present result agrees with available work [7]. The dimensionless governing equations are solved analytically by perturbation method. The effects of various parameters were discussed. From the study its concludes that:
i. Increase in thermal radiation parameter, Schmidt number, magnetic field parameter chemical reaction, decreases velocity, temperature and concentration.
ii. Thermal Grashof number increases the velocity.
iii. Thermal Grashof number (Gr), and sustention parameter (N), enhances skin friction , while increase in chemical reaction parameter (Rc), magnetic field parameter (M), thermal radiation parameter (R), Schmidt number (Sc), and permeability parameter (K), retard skin friction. It is noticed from the table that an increase in Pr, S and δ decreases the rate of heat transfer and increase in radiation parameter (R), increases the rate of heat transfer.
