A turbojet engine is shown in the figure below. The conditions at State 1 are 300K, 100 kPa. The pressure ratio on the compressor is 25. Both the compressor and turbine are adiabatic and reversible. Sufficient heat is added to take Point 3 to 1700 K (constant pressure combustor). In the engine, the turbine produces only enough work to drive the compressor, and no more. This means the pressure at Point 4 is above 100 kPa, and it is | this pressure that is expanded across the nozzle to provide thrust at Point 5. Using air standard assumptions, find the pressure (kPa) and temperature (K) at Point 4. 冊 qlin 3 Combustor Compressor Turbine 5
