(power cycle) your new boss announces at a team meeting that she has developed atechnology that will perform a power cycle that operates between hot and cold reservoirs at 902 °c and 22 °c that produces a power output of 28 kw while receiving 150,000 kj/hof energy via heat transfer from the hot reservoir. you are suspicious that this cyclesounds too good to be true, so you decide to check. what do you find

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.
