Application range of rotary compressors: flow rate and pressure level Rotary (positive-displacement or dynamic) compressors are typically selected to deliver which combination of flow and pressure? Choose the best description.

Difficulty: Easy

Correct Answer: Large quantities of air at low pressures

Explanation:

Concept/Approach
Rotary machines (roots, screw, centrifugal, axial) are well suited for large flow rates. In typical single-stage practice, they achieve moderate to low pressures compared with multistage reciprocating compressors used for very high pressures.


Final Answer
Large quantities of air at low pressures
