Part A Air (use the IG model) enters the compressor of an ideal air standard Brayton cycle at 100 kPa 290 K and a mass flow rate (m) of 3 kg/s. The compressor pressure ratio is 10. The turbine inlet temperature is 1500 K A regenerator with an effectiveness of 70% is incorporated in the cycle. The heat addition can be assumed to take place from a reservoir at 1800 K. (Figure 1) Perform an exergy inventory of the exergy flow rate from the reservoir. Express your answer to four significant figures and include the appropriate units. NA 圖] ?
