A regenerative gas turbine with intercooling and reheat operates at steady state. Air enters the compressor at 100 kPa, 300 K with a mass flow rate (m⋅) of 8 kg/s.
The pressure ratio across the two stage compressor and two stage turbine is 12. The intercooler and reheater each operate at 300 kPa. At the inlets to the turbine stages the temperature is 1500 K. The temperature at the inlet to the second compressor stage is 300
K. The efficiency of each compressor is 85%, and turbine stage is 80%. The regenerator effectiveness is 75%. Determine
(a) The net power developed. Use the IG model.
(b) The thermal efficiency (ηth),
(c) The back work ratio and
