Q2/ A regenerative-reheat cycle has air entering at 1 bar, 300 K into compressor having intercooling in between the two stages of compression. Air leaving first stage of compression is cooled upto 290 K at 4 bar pressure in intercooler and subsequently compressed upto 8 bar. Compressed air leaving second stage compressor is passed through a regenerator having effectiveness of 0.80. Subsequent combustion chamber yields 1300 K at inlet to turbine having expansion upto 4 bar and then reheated upto 1300 K before being expanded upto 1 bar. Exhaust from turbine is passed through regenerator before discharged out of cycle. For the fuel having heating value of 42000 kJ/kg determine fuel-air ratio in each combustion chamber, total turbine work and thermal efficiency. Consider compression and expansion to be isentropic and air as working fluid throughout the cycle.
