63 m3/s of air enters a combustion chamber of a jet engine at a velocity of 381 m/s at -25 °℃ and 35 kPa. The air leaves the chamber at 1,117 m/s at 396 °C. Determine the fuel (in kg) consumed during a 30 minute flight. Assume that changes in air mass flow rate through the chamber are not significant and Ah CpAT. Take the air gas constant to be 0.287 (kPam3)/(kgK), the specific heat at constant pressure of air to be 1 kJ/(kgK) and the heating value of the fuel to be 43,875 kJ/kg. Give your answer to the nearest kg. 63 m3/s of air enters a combustion chamber of a jet engine at a velocity of 381 m/s at -25 °℃ and 35 kPa. The air leaves the chamber at 1,117 m/s at 396 °C.
