(B) A furnace wall is composed of three layers, 10 cm of fire brick (k= 1.56 W/m. K), followed by 23 cm of insulating brick (k= 0.037W/m. K) and 5cm of masonry brick (k= 1 W/m. K). The temperature of the inner wall surface is 1370K and the outer surface is at 360K. Calculate the rate of heat transfer per unit area and the interface temperatures.

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.
