surface roughness

A two layer wall is made of two metal plates with a surface roughness of about 25 microns and is pressed together at an average pressure of about 8 MPa. The first layer is stainless steel with a thickness of 3 mm and thermal conductivity of 14 W/m-K. The second layer is aluminum with the thickness of 13 mm and a thermal conductivity of 237 W/m-K. On the stainless steel side of the wall, the surface is subjected to a heat flux of 788 W/m2 . On the aluminum side of the wall, the surface experiences convection heat transfer at an ambient temperature of 20?C, where the convection coefficient is 11 W/m2 - K. Determine the surface temperature of the steel plate.
