The handle itself is made of low carbon steel, and will have a plastic grip attached to it that is comfortable to grasp. Before selecting a plastic, it is necessary to have information on the temperature of the carbon steel handle. The carbon steel 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 T∞ is 30 oC, and the temperature at the base of the handle reaches T0 = 100 oC. The convective heat transfer coefficient h is 8 W/m2·K and k = 43 W/m·K for low carbon steel. Can you derive the differential equation for the temperature of handle with x as a spatial variable and determine the temperature of handle at the position of 40 mm from the base. Using the general solution attached.
