🔍 Key Concepts

• Role of an intercooler in a multi-stage compressor for a gas turbine cycle • Purpose of a recuperator (heat exchanger) in recovering exhaust heat • How changes in compressor work and fuel required for turbine inlet temperature affect overall cycle efficiency

💭 Think About

• For an intercooled compressor, what happens to the air temperature entering the high‑pressure compressor, and how does that change the power needed to compress it? • For a recuperator, is the exhaust heat used to raise or lower the temperature of the compressed air going into the combustor, and what does that do to the fuel needed to reach the same turbine inlet temperature? • Looking at each option, which combination both reduces compressor work and reduces fuel consumption for the same turbine inlet temperature?

✅ Before You Answer

• Identify which choices say the intercooler reduces high‑pressure compressor power and which say it increases it. • Check whether the recuperator in each choice is said to decrease required fuel or to change the turbine inlet temperature instead. • Confirm that higher cycle efficiency comes from lower total input (compressor work + fuel) for the same turbine inlet temperature and power output.

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.

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.

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.
