Air flows steadily adiabatically through a pipe with a constant cross-sectional area. Air is fed into the pipe through an isentropic converging nozzle from a large tank where the pressure and temperature are 900 kPa and 300 K, respectively, as shown in the figure below. The pressure at the inlet of the duct is 750 kPa. If the temperature at the duct exit is 275 K, determine the pressure at the duct exit. Ans. pe = 568.7 KPa
