A pure jet engine propels an aircraft at 240 m/s through air at 45 kPa and -13 C. The inlet diameter of this engine is 1.6 m, the compressor ratio is 13, and the temperature at the turbine inlet is 557 C. Determine the velocity at the exit of this engine's nozzle and the thrust produced. Assume ideal operation for all components and constant specific heats at room temperature.
