Concept explainers
Heat transfer. In a study of heat transfer in a grid of wires, the at an exterior node is maintained at a constant value (in °F) as shown in the accompanying figure. When the grid is in thermal equilibrium, the temperature at an interior node is the average of the temperatures at the four adjacent nodes. For instance.
