Students did an experiment on Swansea University jet engine. They measured ambient temperature 16 deg C and ambient pressure 1.02 bar, engine RPM 49,042, thrust 11.1328 N, air flow 23.2031 l/s, fuel flow 6.7383 l/h, gauge combustion pressure 0.1599 bar. The temperature values (deg C) at compressor exit, turbine inlet and exhaust were recorded as 31.64, 901.75, 568.35. Assume density of fuel as 0.8 kg/L. The heating value of fuel is 42,580 kJ/kg. The idea gas constant R is 0.287 kJ/kg K, the Cp value for air is 1.005 kJ/kg K and the value of specific heat ratio k is 1.4. What is the maximum fuel (thermal) efficiency for any engine operating between the measured maximum and minimum temperature limits can achieve?
