A surface with an area of 2 m² is at 400°C and is exposed to surroundings at 60°C and convects andradiates heat to the surroundings. The convection coefficient is 80 W/m²K. The radiation factor isone. If the heat is conducted to the surface through a solid of conductivity 12 W/mK. Calculate theheat convected by the surface and the radiated heat. 8. In relation to the previous Q7, please write down the energy balance and calculate thetemperature gradient at the surface in the solid.
