An insulated steam pipe is covered with two layers of insulation as seen figure below. Draw the thermal resistance network. Develop a formula to calculate the heat transfer rate per unit length of the pipe. How can you determine the temperature difference AT across the pipe wall and second insulation layer. T = 250°C, Ins.2 Ins.1 Pipe - T2 = 20°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.
