In comparing a centrifugal-type to an axial-type compressor, which of the following statements is true?

Correct Answer: Option C — Centrifugal compressors have a higher compression ratio per stage than an axial flow compressor.

Centrifugal compressors achieve a significantly higher pressure ratio per stage compared to axial flow compressors. While axial compressors are more efficient for high-mass-flow applications, centrifugal designs are preferred for smaller engines or auxiliary power units due to their ruggedness, simplicity, and superior pressure rise capability in a single stage.
