1, Two parallel disks, 80 cm in diameter, are separated by a distance of 10 cm and completely enclosed by a large room at 20°C. The properties of the surfaces are T1 = 620°C, E, = 0.9, T2= 220°C, E2= 0.45. What is the net radiant heat transfer with each surface? (Do not include back side exchange, only that from the surfaces facing each other.)

Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.
