Air flows in a convergent-divergent nozzle. The total pressure and temperature are \( 4 \mathrm{MPa} \) and \( 500 \mathrm{~K} \) respectively. The exit area and throat area are \( 0.00152 \mathrm{~m}^{2} \) and \( 0.001 \mathrm{~m}^{2} \) respectively. The exit temperature \( T_{E} \) is \( 491.15 \mathrm{~K} \). The speed of sound at the throat section is (in \( \mathrm{m} / \mathrm{sec} \) ), 400 440 480 520 560
