You want to figure out whether it is safe to touch the outsid surface of the pipe in question. Here are the details: "A stainless steel pipe is carrying hot water to test facility. The inside surface of the pipe is at a temperature of 70°C and the inner radius is 0.2 m The thickness of the steel pipe is 12 mm. It is exposed to air at 30°C on the outside. The averag convection coefficient of air over the pipe is 15 W/m². C. Thermal conductivity of steel is 54 W/m.º Negelect radiation. Consider steady conditions." Calculate, assuming a 1-m long pipe segmen, th temperature of the outside surface of the pipe.
