Question
Transcribed Image Text: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.
