A heat generating device is insulated, with one circular face (D = 15 mm) exposed to air at 25°C with convection coefficient 40 w/m²K. Heat rate generation is 0.4 W. A fin (short tube) with 15 mm OD, 14 mm ID and 20 mm length is attached to the device. The conductivity of the fin material is 175 W/mK. Determine the surface temperature before and after adding the fin. K To, hoo 10 OD o 20
