An aluminum plate and a stainless steel plate are pressed against each other at an average pressure of 20 MPa. Both plates have a surface roughness of 2 um. Determine the Impact on the temperature drop at the Interface if the surface roughness of the plates is Increased by tenfold. If the surface roughness of the plates is increased by tenfold, then the temperature drop at the interface would decrease by about a factor of six. If the surface roughness of the plates is Increased by tenfold, then the temperature drop at the Interface would increase by about a factor of eight. If the surface roughness of the plates is Increased by tenfold, then the temperature drop at the interface would increase by about a factor of six. x If the surface roughness of the plates is Increased by tenfold, then the temperature drop at the Interface would decrease by about a factor of eight.
