Rotary compressors: suitability for flow rate and pressure level. Evaluate the statement about application range: rotary compressors are preferred when a large volume flow is needed at relatively low delivery pressure. Decide if this statement is correct or incorrect.

Difficulty: Easy

Agree
Disagree
Correct only for reciprocating compressors
Correct only for axial machines

Correct Answer: Agree

Explanation:

Concept/Approach
Rotary (centrifugal/axial/rotary vane/roots) compressors are commonly used for large volumetric flow rates at modest pressure ratios, where reciprocating compressors become bulky and pulsating. Hence the statement is correct.

Final Answer
Agree.
