Air at \(1 \mathrm{~atm}\) and \(310 \mathrm{~K}\) enters a 2 -m-long rectangular duct with cross section \(80 \mathrm{~mm} \times 160 \mathrm{~mm}\). The duct is maintained at a constant surface temperature of \(430 \mathrm{~K}\), and the air mass flow rate is \(0.09 \mathrm{~kg} / \mathrm{s}\). Determine the heat transfer rate from the duct to the air and the air outlet temperature.
