A straight fin of rectangular profile is constructed of stainless 18-8 steel and has a width of 5 cm and thickness of 2.5 cm. The base temperature is maintained at 100°C and the fin is exposed to a convection environment at 20°C with h = 47 W/m2K. Calculate the heat lost by the fin of one meter length.
