One-dimensional heat transfer through a composite wall is shown in the following figure. Please calculate the heat flow through the composite wall according to the equivalent thermal circuit. It is known that the thermal conductivity are ka-46.5 W/(m.K), kp=1.1 W/(m.K), kc =0.06 W/(m.K), respectively. The thickness of the three materials is Ax=Axg=Axc=10mm. The temperature of wall 1 and wall 4 are t=80°C, t4=15°C, respectively. (Please give the compution process and the result.) - Temperature profile RA Rg Axg I3 Axc T4 A B 2 3 4 Figure for question 9

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.
