A small oven with a surface area of 3 ft2 is located in a room in which the walls and the air are at a temperature of 80?F. The exterior surface of the oven is at 300?F and the net heat transfer by radiation between the oven??s surface and the surroundings is 2000 Btu/h. If the average convective heat transfer coefficient between the oven and the surrounding air is 2.0 Btu/(h ft2 ?F), calculate:(a) The net heat transfer between the oven and the surroundings in Btu/h,(b) The thermal resistance at the surface for radiation and convection, respectively, in (h ?F)/Btu, and(c) The combined heat transfer coefficient in Btu/(h ft2 ?F).GIVENSmall oven in a roomOven surface area (A) = 3 ft2Room wall and air temperature (T??) = 80?FSurface temperature of the exterior of the oven (To) = 300?FNet radiative heat transfer (qr) = 2000 Btu/hConvective heat transfer coefficient ( hc ) = 2.0 Btu/(h ft2 ?F)ASSUMPTIONSSteady stateprevails
