Combustion gases with an average specific heat ratio of k=1.33 and a gas constant of R=0.280 kJ/kgK enter a 10-cm-diameter adiabatic duct with inlet conditions of Ma1=2,21 T1=521 K, and P1 =182,1 kPa. If a normal shock occurs at a location 2021 mm from the inlet, determine the velocity, temperature, and pressure at the duct exit. Take the average friction factor of the duct to be 0.01021. Calculate the static stagnation pressure, temperature and density values of the flow at the duct outlet.

Solve the problem by making the necessary assumptions and drawing the schematic figure.
