Question

A straight rectangular fin has a length of 20 mm and a thickness of 1.5 mm. The thermal conductivity is 60 W/(mK), and it is exposed to a convection environment at 20°C and h = 500 W/(m2K). Calculate the maximum possible heat loss per metre of fin depth for a base temperature of 200°C. What is the actual heat loss?
