At a section where nozzle area is 0.0012 m², the local pressure, temperature and Mach number are 4.1 bars, 4.4 °C and 0.52 respectively. The back pressure is 2.06 bar. The Mach number at the throat, the mass flow rate, and the throat area are to be determined.

A turbine nozzle vane at high speed exhibits a normal shock. The flow is modelled as analogous to that through a convergent-divergent de Laval nozzle with a normal shock at the nozzle exit. Just upstream of the shock, the exit Mach number Me = 1.09, the absolute static pressure pe = 280 kPa, the static temperature Te = 586 K, the ratio of specific heats of the combustion productsk = 1.35, and the constant pressure specific heat capacity Cp = 1027 J-kg "K-1. Assuming the combustion products are constant property ideal gasses, determine the density of the combustion products pp after the shock.
