QUESTION 12 The flow discharge from turbine stator nozzle guide vanes is modelled as an isentropic discharge through a fully expanded de Laval nozzle. At high speed operations, the passage throat is choked and the throat cross-sectional area A* = 219 cm2. The nozzle exit Mach number Me = 1.11. Assuming the combustion products have a constant specific heat ratio k = 1.39, determine the nozzle exit cross-sectional area A. State your answer in cm2 to two decimal places and enter the numerical value only. Partial credit is awarded for a reasonable approximation to the correct numerical answer.
