Performance of a compressor needs to be analyzed. Air enters the compressor of an air- standard Brayton cycle at 100 kPa, 300 K, with a volumetric flow rate of 5 m'/s. The turbine inlet temperature is 1400 K. The efficiency of the compressor is 70%. For compressor pressure ratios of 8, (draw layout and T-s diagram) analyze: a. The thermal efficiency of the cycle. b. Outline and compare the effect on cycle efficiency, if compression ratio is increased beyond 8?

Question
Performance of a compressor needs to be analyzed. Air enters the compressor of an air- standard Brayton cycle at 100 kPa, 300 K, with a volumetric flow rate of 5 m/s. The turbine inlet temperature is 1400 K. The efficiency of the compressor is 70%. For compressor pressure ratios of 8, (draw layout and T-s diagram) analyze: a The themal efficiency of the cycle. b. Outline and compare the effect on cycle efficiency, if compression ratio is increased beyond 8? Dodecane (C1H26) burns completely with 150% of theoretical air. Analyze its performance on the basis of Air-fuel ratio on a molar and mass basis.
