Question:

Air enters the compressor of an ideal air standard Brayton cycle at 100 kPa, 25oC with a volumetric flow rate of 8 m3/s and is compressed to 1000 kPa. The temperature at the inlet to the first turbine stage is 1000oC. The expansion takes place is entropically in two stages, with reheat to 1000oC between the stages at a constant pressure of 300 kPa. If a regenerator having an effectiveness of 100% is incorporated in the cycle, determine (a) The thermal efficiency of the cycle (ηth,Brayton). Use the PG model.
