Q) A steel pipe (K = 45.0 Wm.K) having a 0.05 m O.D is covered with a 0.042 m thick layer of magnesia (K = 0.07 W/m.K) which turn %3D covered with a 0.024 m layer of fiber glass insulation (K=0.048 W/m.K). The pipe wall outside temperature is 370 K and the outside surface temperature of the fiber glass is 305 K. What is the interfacial temperature between the magnesia and fiber glass? Also calculate the steady state heat transfer.

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.
