In a gas turbine power plant, the gas enters the five-stage compressor at 300 K. The overall power ratio is 20. After the compression, the gas enters a regenerator with an effectiveness of 80%. For preheating, it is further heated in a combustion chamber until it reaches a temperature of 1600 K. The heated gas expands to the first turbine stage and is reheated to 1550 K. The temperatures after the reheating processes are...
