40m3/s of air enters a combustion chamber of a jet engine at a velocity of 336m/s at 24C and 38kPa. The air leaves the chamber at 1,141m/s at 237C. 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 hCPT. Take the air gas constant to be 0.287 (kPam3)/(kgK) , the specific heat at constant pressure of air to be 1kJ/(kgK) and the heating value of the fuel to be 59,805kJ/kg. Give your answer to the nearest kg
