A Gas Turbine Power Plant receives air at 14 psia, 80F. Air is partially compressed to 55 psia and cooled to a temperature difference of 60 F and then compressed to a final pressure of 105 psia. Hot gas enters the turbine at 1460 F and is used to preheat compressed air. Internal efficiency of the turbine is 90% and compressor is 88%. Mechanical efficiency for both is 85 %. Generator efficiency is 95%. The regenerator effectiveness is 60 % and the combustor efficiency is 90 %. Fuel is having a specific gravity of 0.927 at 77 F. Determine the plant thermal efficiency.
