QUESTION 3 flow rate m c A twin-spool gas turbine of bypass ratio 7.7 propels an aircraft at the speed Uin = 95 m-s-1. The engine core mass = 6.4 kg-s-1. The exhaust gasses leave the core nozzle at the axial velocity ucout = 246 m-s-1 and the bypass nozzle exit velocity. ubout = 140 m-s-1. Fuel is added at the rate of 381 kg-n-1. Assuming the core mass flow rate is constant, evaluate the thrust specific fuel consumption. State your answer in kg-n-1N-1 to 3 decimal places and enter the numerical value only. Partial credit is awarded for a reasonable approximation to the correct numerical answer.
