5. A turbojet with a 1-m diameter inlet is being tested in a facility capable of simulating high-altitude conditions where the pressure is 55kPa absolute and the temperature at the

exit is 800 K. The gas constant for air is 287 J/kg.K. The velocity at the inlet is 100m/s. Assuming ideal gas law is applicable, what is the density of the fluid at the exit? What is the mass flow rate? [similar to Chapter 1-ldeal Gas]100 m/sT0.75 m
