A centrifugal compressor is suitable for which of the following?
- A. High pressure ratio, low mass flow
- B. Low pressure ratio, low mass flow
- C. High pressure ratio, high mass flow
- D. Low pressure ratio, high mass flow
Answer: D. Low pressure ratio, high mass flow
Explanation: A centrifugal compressor is characterized by a high mass flow rate and a relatively low pressure ratio per stage. In contrast, reciprocating compressors are used for low mass flow rates and high pressure ratios.
