Consider atmospheric air at \(20^{\circ} \mathrm{C}\) and a velocity of \(30 \mathrm{~m} / \mathrm{s}\) flowing over both surfaces of a 1-m-long flat plate that is maintained at \(130^{\circ} \mathrm{C}\). Determine the rate of heat transfer per unit width from the plate for values of the critical Reynolds number corresponding to \(10^{5}, 5 \times 10^{5}\), and \(10^{6}\).
