Problem 9.35: air enters the compressor of an ideal air-standard brayton cycle at 100 kpa, 300 k, with a volumetric flow rate of 5 m3/s. the turbine inlet temperature is 1400 k. for compressor pressure ratios of 6, 8, and 12, determine (a.) the thermal efficiency of the cycle. (b.) the back work ratio. (c.) the net power developed, in kw.
