Answer:
500 to 10,000
Explanation:
Centrifugal pump impellers have specific speed values ranging from 500 to 10,000 (English units), with radial flow pumps at 500-4000, mixed flow at 2000-8000, and axial flow pumps at 7000-20,000. Values of specific speed less than 500 are associated with positive displacement pumps.
