A turbojet aircraft flies with a velocity of 260 m/s in through air at -40°C and 35 kPa. The compressor pressure ratio is 10 while hot gasses at 1350 K enter the turbine at a mass flow rate of 45 kg/s. Assume the cold-air-standard and that the diffuser, compressor, turbine, and nozzle are all isentropic. Report your answers to four significant digits using rounding. Report the temperature of the air after the diffuser in K rounded to one decimal place. Report the temperature of the air after the compressor in K rounded to one decimal place.
