Q4 A narrow-body passenger aircraft is powered by twin turbofan jet engines. Its cruising altitude is 33000 ft and flying Mach number is 0.85. The propulsive efficiency is 85%. If the total mass flow rate going through the engine is 5yz kg/s (note the last 2 digits in the mass flow rate are taken from the last two digits of your student ID: 20uvwxyz). Assume that the fuel flow rate is much smaller than the airflow rate. a) Calculate the jet velocity. [5] b) Calculate the gross thrust and the net thrust. [5]
