Consider a large 5-cm-thick brass plate (k = 111 W/m·°C) in which heat is generated uniformly at a rate of 2×105 W/m3. One side of the plate is insulated while the other side is exposed to an environment at 25 °C with a heat transfer coefficient of 44 W/m2·°C. (Hint: The heat transfer surfaces of the large plane walls considered in our lecture have the same temperature. The formula is slightly adjusted for this question.) Where is the maximum temperature located? What is the value of the maximum temperature in °C?

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.
