Question:
Air at \(4 \times 10^{-4} \mathrm{~kg} / \mathrm{s}\) and \(20^{\circ} \mathrm{C}\) enters a rectangular duct that is \(1 \mathrm{~m}\) long and \(4 \mathrm{~mm} \times 16 \mathrm{~mm}\) on a side. A uniform heat flux of \(500 \mathrm{~W} / \mathrm{m}^{2}\) is imposed on the duct surface. What is the temperature of the air and of the duct surface at the outlet?
