The door of an oven in the kitchen of a house is 0.5 m high and 0.7 m wide. When the oven is operating, the outside temperature of the door reaches 32°C. Calculate the heat transfer from the oven door towards the room at 22°C, taking into account the effects of radiation. The emissivity of the oven door is 1 and the walls of the kitchen are at 22°C. (σ = 5.67 x 10-8 W/m 2K4 , g = 9.81 m/s2 ) NOTE: More precise values for weather characteristics can be obtained from resources on the internet. Also indicate the source you received.
