Two 3 cm -diameter 304 stainless-steel bars, 10 cm long, with a surface roughness of about 1 m are pressed together with a pressure of 50 atm and the two-bar combination is exposed to an overall temperature difference of 100 C. Calculate the axial heat flow and temperature drop across the contact surface. The contact resistance is 0.747 C/W. (Use thermal-resistance approach.)
