a Air at -40 °C enters a jet combustion chamber with a velocity equal to 150 m/s. The exhaust velocity is 200 m/s, with 297 °C as outlet temperature. The mass flow rate of the gas (air-exhaust) through the engine is 7.6 kg/s. The heating value of the fuel is 45.9 MJ/kg and the combustion (to be considered as an external source) has an efficiency equal to 100%. Assume the gas specific heat at constant pressure (cp) to be 1.25 kJ/(kg K). Determine the kg of fuel required during a 4.8 hours flight to one decimal value.
