6. In a long rectangle fin, its material has thermal conductivity of 200 w/ m.K and is subjected to natural convection heat transfer where the convection heat transfer coefficient is 27.5 W/m 2.K. Its perimeter is 20 cm and its cross section area is is 16 cm?. If the base temperature is 90°C and the environmental temperature is 20 °C; Find the convection heat transfer from the fin. Also Prove that the convection heat transfer is equal to the heat conduction from its base
