A regenerative gas turbine with intercooling and reheat operates at steady state conditions. Air enters the compressor at 100 kPa, 300 K, with a mass flow rate of 5.8 kg/sec. The pressure ratio across two stage compressor is 10:1. The pressure ratio across two stage turbine is also 10:1. The intercooler and reheater each operate at 300 kPa. At the inlets to the turbine stages, the temperature is 1400 K. Second compression is at 300 K. The efficiency of each compressor and turbine stage is 80%. The regenerative efficiency is 80%.

Determine;

(a) Thermal efficiency of the cycle

(b) The back work ratio

(c) The net power delivered in kW
