🔍 Key Concepts

• Role of the impeller in adding kinetic energy (velocity) to the air • Purpose of a diffuser or volute in a centrifugal compressor • Difference between increasing velocity vs increasing static pressure

💭 Think About

• Which part of the compressor directly spins and throws the air outward, and what property does that mainly change? • After the air leaves the rotating section, what stationary component is designed to slow the air down and convert kinetic energy into pressure? • Among the options, which component is specifically shaped (passages/flow area changes) to reduce velocity and raise static pressure?

✅ Before You Answer

• Identify which component is rotating versus stationary • Determine which component’s main function is to add velocity and which is to convert velocity into pressure • Eliminate any option whose primary use is not in centrifugal compressors or not for pressure recovery
