Q

Which of the following statements is true regarding centrifugal compressors?

🔍 Key Concepts

• Centrifugal vs. axial compressors: basic advantages, typical applications, and size/power ranges • Flow direction in an impeller: where air enters (axial vs radial) and where it leaves in a centrifugal compressor • Design simplicity and efficiency: which type is generally simpler/lighter and which tends to have higher efficiency for large gas turbines

💭 Think About

• Think about how air actually flows through a centrifugal impeller: does it come in along the shaft (axial) or from the side (radial), and how does it exit? • Consider which type of compressor you would expect on large, high-power marine gas turbines vs. small auxiliary units—what does that suggest about weight, complexity, and common usage? • Compare which compressor type is usually chosen when maximum efficiency is needed in modern high-power turbines—does that match any of the statements?

✅ Before You Answer

• Verify the direction of flow at the inlet and discharge of a centrifugal impeller (axial vs. radial). • Check typical applications of centrifugal compressors: are they more common on small/lower-power or large/high-power gas turbines? • Confirm general trends in efficiency: is a centrifugal compressor usually more efficient than an axial compressor in large turbine applications, or the other way around?
