Question 1 of 27070

The high air velocity leaving the air impeller of an exhaust gas turbocharger is converted to pressure in the __________.

🔍 Key Concepts

• Centrifugal compressor / blower theory – where does high-velocity air from the impeller go next? • Velocity vs. pressure – which component is designed primarily to slow the flow down and increase static pressure? • Typical parts of a turbocharger: inlet nozzle ring, turbine wheel, diffuser, volute (scroll)

💭 Think About

• Think about which part of the air side is shaped to gradually slow the air while maintaining smooth flow, so that kinetic energy (velocity) becomes pressure. • Ask yourself: which component mainly accelerates the air, and which component mainly converts that high speed into higher static pressure? • Consider which of these parts is usually made of a set of passages or channels surrounding the impeller and is specifically designed for pressure recovery.

✅ Before You Answer

• Identify which listed components are on the turbine (exhaust gas) side versus the compressor (air) side of the turbocharger. • Determine which component is characterized by multiple passages or channels arranged around the impeller to recover pressure. • Eliminate any parts whose main job is to direct or accelerate flow into a wheel, rather than slow it down and increase pressure.
