5. A small oven is located in a room in which the walls and the air are at a temperature of (25 + CN) °C. The exterior surface of the oven is at (170+CN) °C and the net heat transfer by radiation between the oven's surface and the surroundings is 586 W. If the average convective heat transfer coefficient between the oven and the surrounding air is 11- Consider that the surface area of the oven as0.28 m?. m2-K calculate: (a) the net heat transfer between the oven and the surroundings in W, (b) the thermal resistance at the surface for radiation and convection, respectively, in KW, and (c) the combined heat transfer coefficient in - m2-K
