A regenerative gas turbine with intercooling and reheat operates at steady state. Air enters the compressor at 100kPa,300K with a mass flow rate of 5.807. The pressure ratio across the two-stage compressor is 10 . The pressure ratio across the two-stage turbine is also 10. The intercooler and reheater each operate at 300kPa. At the inlets to the turbine stages, the temperature is 1400K. 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%. Determine:

(a) the thermal efficiency
(b) the net power developed, in W.
