Which of the following can be used to create a flow of gas, where no significant compression is required ?
Correct answer: B. Blower
- A. Reciprocating compressor
- B. Blower
- C. Axial flow compressor
- D. Centrifugal compressor
Explanation
A blower produces gas flow with a relatively small pressure rise, so substantial compression is not required. Compressors are used when a much larger pressure increase is needed.
