Consider a straight cylindrical rod aluminum fin with 2 cm diameter on aluminum wall have ground surfaces and are exposed to air with a surface roughness of about 100 pin. The fin length is 10 cm, and the convection environment is at 20°C, and h- 125 W/m C. Calculate the heat transfer for fin on a wall with temperature of 200°C. What percentage reduction in heat transfer is caused by the contact conductance?
