A fin has $$5mm$$ diameter and $$100mm$$ length. The thermal conductivity of fin material is $$400W/m K.$$ One end of the fin is maintained at $${130^ \circ }C$$ and its remaining surface is exposed to ambient air at $${30^ \circ }C.$$ if the convective heat transfer coefficient is $$40W/{m^2}K,$$ the heat loss (in $$W$$) from the fin is
