Q-4: In an industrial gas turbine plant, air is compressed through a pressure ratio of 5/1 starting from 300 K. The air then enters a regenerating heat exchanger of 80% effectiveness. The air leaving the heat exchanger and enters the combustion chamber to reach a maximum temperature of 1100 K. The isentropic efficiency of the compressor and the turbine is 87.5% and 89.3 % respectively. The air mass flow rate of 10 kg's suffers a pressure drop of 0.02 bar through the combustion chamber. For these conditions find: • Power output of the plant. • Thermal cycle efficiency. • Work ratio.
