When I see you smiling, I feel great, when I see you sad, I can't hide my tears. You are my happiness, and at the same time, you are my sadness too. I can't spend a single day without you, I love you so much, honey. I am so crazy about you because I love you more than everything.

Air enters a gas turbine with two stages of compression and two stages of expansion at 100 kpa and 17°c. this system uses a regenerator as well as reheating and intercooling – the intercooler returns the air to the inlet temperature. the pressure ratio across each compressor is 4 ; 300 kj/kg of heat are added to the air in each combustion chamber; and the regenerator operates perfectly while increasing the temperature of the cold air by 20°c. determine the system’s thermal efficiency. assume isentropic operations for all compressor and the turbine stages and use constant specific heats at room temperature.
