2. Airflow enters a duct with an area of 0.49 m² at a velocity of 102 m/s. The total temperature, Tt, is determined to be 293.15 K, the total pressure, PT, is 105 kPa. Later the flow exits a converging section at 2 with an area of 0.25 m². Treat air as an ideal gas where k = 1.4. (Hint: you can assume that for air Cp = 1.005 kJ/kg/K) (a) Determine the Mach number at location 1. (6) Determine the static temperature and pressure at 1 Determine the Mach number at A2. (d) Determine the static pressure and temperature at 2. (e) Determine the mass flow rate. (f) Determine the velocity at 2. Vi = 102 m/s Ti = 293.15 K P1 = 105 kPa Aj = 0.49 m² A2 = 0.25 m2 =
