QUESTION 11 The flow expansion through turbine stator nozzle guide vanes is modelled as an isentropic discharge through a fully expanded de Laval nozzle. The nozzle inlet stagnation temperature To7 = 844 K and the stagnation pressure pon = 607 kPa. The nozzle exit static pressure pg = 544 kPa. The combustion products have specific heat ratio k = 1.30 and constant pressure specific heat capacity Cp = 1146 J-kg-1K-1. Determine the nozzle exit velocity V2. State your answer in m-s-7 to zero decimal places and enter the numerical value only. Partial credit is awarded for a reasonable approximation to the correct numerical answer.
