Engine: Gas Turbines

1. A The intercooler serves to reduce the required high-pressure compressor power, while the recuperator utilizes waste heat from the exhaust to decrease turbine inlet temperature.
2. B The intercooler serves to reduce the required high-pressure compressor power, while the recuperator utilizes waste heat from the exhaust to decrease required fuel to achieve the turbine inlet temperature.
3. C The intercooler serves to increase the required high-pressure compressor power, while the recuperator utilizes waste heat from the exhaust to increase turbine inlet temperature.
4. D The intercooler serves to increase the required high-pressure compressor power, while the recuperator utilizes waste heat from the exhaust to decrease turbine inlet temperature.
