2-58 Consider a solid cylindrical rod of length 0.15 m and diameter 0.05 m. The top and bottom surfaces of the rod are maintained at constant temperatures of 20°C and 95°C, re- spectively, while the side surface is perfectly insulated. Deter- mine the rate of heat transfer through the rod if it is made of 380 W/m - °C, (b) steel, k = 18 W/m - °C. and (a) copper, k %3D

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.
