WebJan 22, 2024 · Heat radiation (infrared) is emitted by a hot object in roughly randomly all directions, so only a small part of the total radiation will hit the object. And some of it will simply be reflected by it, especially if the object is shiny. Convective heat tends to rise vertically, so most of it reaches the overhead object. WebSep 12, 2024 · Example 1.7. 1: Calculating Heat Transfer through Conduction A polystyrene foam icebox has a total area of 0.950 m 2 and walls with an average thickness of 2.50 cm. The box contains ice, water, and canned beverages at 0 o C. The inside of the box is kept cold by melting ice.
