Question:

A straight rectangular fin has a length of 3.5 cm and a thickness of 1.4 mm. The thermal conductivity is 55 W/m ∙ ºC. The fin is exposed to a convection environment at 20ºC and h = 500 W/m2 ∙ ºC. Calculate the maximum possible heat loss for a base temperature of 150ºC. What is the actual heat loss for this base temperature?
