The air flow rate through the gas generator of a turboprop engine is 100 kg/s. The stagnation temperatures at the inlet and exit of the combustor are 600 K and 1200 K, respectively. The burner efficiency is 90% and the heating value of the fuel is 40 MJ/kg. The specific heats at constant pressure (Cp) for air and burned gases are 1000 J/kg-K and 1200 J/kg-K, respectively. The flow rate of the fuel being used is _______ kg/s. (round off to two decimal places). (Note: Do not neglect the fuel flow rate with respect to the air flow rate)
Correct : 2.35 to 2.50
