Derive the following equation for the optimum outside diameter of insulation on a wire for maximum heat loss:

where km, is the mean thermal conductivity of the insulation and (hc + hr)c, is the combined and constant surface heat-transfer coefficient. The values of k, and (hc + hr)c can be considered as constants independent of temperature level and insulation thickness.
