t engine, the emitter, compressor, turbine and nozzle operate at isentropic pressure, while the combustion chamber operates at constant pressure. At the inlet of the emitter, the temperature of the air is 230 K, the pressure is 25 kPa, the flow rate is 30 kg/s and the speed is 200 m/s. Since the pressure of the air at the compressor outlet is 500 kPa, the temperature of the air at the turbine inlet is 1000 K and the pressure of the air at the nozzle outlet is 25 kPa, a) Draw the flow diagram of the cycle schematically. b) Find the velocity of the gases at the nozzle exit. c) Find the amount of heat supplied to the combustion chamber. d) Find the reaction force, reaction force and reaction efficiency

Question
In a jet engine, the emitter, compressor, turbine and nozzle operate at isentropic pressure, while the combustion chamber operates at constant pressure. At the inlet of the emitter, the temperature of the air is 230 K, the pressure is 25 kPa, the flow rate is 30 kg/s and the speed is 200 m/s. Since the pressure of the air at the compressor outlet is 500 kPa, the temperature of the air at the turbine inlet is 1000 K and the pressure of the air at the nozzle outlet is 25 kPa,
a) Draw the flow diagram of the cycle schematically.
b) Find the velocity of the gases at the nozzle exit.
c) Find the amount of heat supplied to the combustion chamber.
d) Find the reaction force, reaction force and reaction efficiency.
