An isentropic converging-diverging nozzle feeds an insulated constant area duct, as shown in the figure. There is a normal shock wave in the duct which discharges into a region with a pressure of 100 kPa. The duct has a diameter of 0.054 m, while the cross-sectional area of the nozzle throat is 0.001 m2. The stagnation temperature in the nozzle is 303 K. If the average friction coefficient in the duct is 0.0029, determine the exit Mach number and stagnation pressure, and find the air mass flowrate. Normal shock wave

An isentropic converging-diverging nozzle feeds an insulated constant area duct, as shown in
the figure. There is a normal shock wave in the duct which discharges into a region with a
pressure of 100 kPa. The duct has a diameter of 0.054 m, while the cross-sectional area of the
nozzle throat is 0.001 m2. The stagnation temperature in the nozzle is 303 K. If the average
friction coefficient in the duct is 0.0029, determine the exit Mach number and stagnation
pressure, and find the air mass flowrate.
