heat transfer

 

A straight fin of the rectangular profile has a thermal conductivity of \( \left(14 \mathrm{~W} / \mathrm{m},{ }^{\circ} \mathrm{C}\right) \), the thickness of \( (2 \mathrm{~mm}) \), and length of \( (23 \mathrm{~mm}) \). The base of the fin is maintained at a temperature of \( \left(220^{\circ} \mathrm{C}\right) \) while the fin is exposed to a convection environment at \( \left(23^{\circ} \mathrm{C}\right) \) with \( \left(h=25 \mathrm{~W} / \mathrm{m}^{2} .{ }^{\circ} \mathrm{C}\right) \). Calculate the fin heat transfer rate per meter of fin depth
