Air enters the compressor at 100 kPa, 300 K and is compressed to
1000 kPa. The temperature at the inlet to the first turbine stage
is 1400 K. The expansion takes place isentropically in two stages,
with reheat to 1400 K between the stages at a constant pressure of
300 kPa. A regenerator having an effectiveness of 100% is also
incorporated into the cycle. The turbine and the compressor each
