Question:

A turbojet aircraft is flying with a velocity of 350 m/s at an altitude of 9150 m, the ambient conditions are 30 kPa and -30oC. The pressure ratio across the compressor is 10, and the temperature at the turbine inlet is 1200 K. Air enters the compressor at a rate of 30 kg/s, and the jet fuel has a heating value of 42000 kJ/kg. Using the PG model, determine
(a) The velocity of the exhaust gases,
(b) The propulsive power developed and
(c) The rate of fuel consumption.
