A 1-1/2-quart aluminum saucepan has a handle that is riveted to its wall (See Figure ). The handle itself is made of low carbon steel, and will have a plastic pip attached to it that is comfortable to grasp. Before selecting a plastic, it is necessary to have information on the temperature of the aluminum handle. The aluminum handle can be considered as a rod 11 mm in diameter and 45 mm long. When being used over a stove burner, the ambient temperature is 30? and the temperature at the base of the handle reaches 100?. For a convection coefficient, hc = 8 W/m ² , determine and graph the temperature profile. Determine also the heat transferred by the handle.
