In a turbocharger, inlet air velocity is increased in the __________.

Question 1 of 27070

In a turbocharger, inlet air velocity is increased in the __________.

🔍 Key Concepts

• Turbocharger airflow path: order of components from air inlet to compressor outlet • Difference between nozzles (increase velocity) and diffusers (decrease velocity, increase pressure) • Function of impeller vanes versus surrounding stationary parts

💭 Think About

• Think about which component’s main job is to convert pressure energy into higher air velocity rather than the other way around. • Ask yourself: in the compressor section, where is the air being accelerated and where is it being slowed down and compressed? • Which of these listed parts is specifically shaped like a nozzle to speed up the airflow before it reaches the rotating blades or turbine?:

✅ Before You Answer

• Identify which parts are rotating vs stationary and what each typically does to airflow (accelerate vs diffuse). • Recall: a diffuser generally converts velocity to pressure, not the other way around. • Consider which option is normally associated with nozzle action (increasing velocity) in a turbocharger.
