A 1-cm thick, AISI 302 stainless steel wall is insulated with a 5 cm-thick layer of fiberglass (density of 28 kg/m^3) on its outside surface. In a test with ambient air at 300K, the surface temperature of the insulation is 310K. hc for the outside surface is 6 W/m^2 K and the emissivity of the insulation is 0.8. a. Develop a thermal circuit b. Determine the temperature of the inner surface of the stainless steel. Hint: this is a problem where you need to consider materials properties as a function of temperature. see attached tables.

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.
