36 m3/s of air enters a combustion chamber of a jet engine at a velocity of 180 m/s at -55 °C and 40 kPa. The air leaves the chamber at 1,036 m/s at 274 °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 LaTeX: \Delta h\cong C_P\Delta T. Take the air gas constant to be 0.287 kPa. m3/kg. K , the specific heat of air to be 1 kJ/(kgK) and the heating value of the fuel to be 50,963 kJ/kg.
