Question 11 5 Pd The Flow Expansion Through Turbine Stator Nozzle Guide Vanes Is Modelled As An Isentropic Discharge Thr 1 (401.05 KiB) Viewed 33 times

QUESTION 11 5 pd 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 po7 = 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 V8. State your answer in m-s-1 to zero decimal places and enter the numerical value only. Partial credit is awarded for a reasonable approximation to the correct numerical answer.
