A regenerative gas turbine with intercooling and reheating operates at a steady state. Air enters
the compressor at 100 kPa, 300 K with a mass flow rate of 3.25 kg/s. The pressure ratio across
the two-stage compressor is 8.5. The pressure ratio across the two-stage turbine is also 8.5.
The intercooler and reheater each operate at 300 kPa. At the inlets to the turbine stages, the
temperature is 1220 K. The temperature at the inlet to the second compressor stage is 300 K
The isentropic efficiency of each compressor and turbine stage is 80%. The regenerator
effectiveness is 80%. (Note that compressors and turbine efficiencies need to be considered)
Determine:
(a) the cycle thermal efficiency ($\eta_{cycle}$)
(b) the back work ratio (BWR)
(c) the net power developed, in kW ($W'_{cycle}$)
(d) the total rate energy added by heat transfer to the cycle, in kW. ($Q_{in1} + Q_{in2}$)
(e) The heat rejected to the environment in kW ($Q_{out}$)
