Specific speed for a centrifugal pump is___________________?
Correct answer: A. N √Q/H3/4
- A. N √Q/H3/4
- B. N √Q/H2/3
- C. N3D5/H1/3
- D. N √Q/H
Explanation
The specific speed of a centrifugal pump is defined as N√Q divided by H^(3/4), using consistent units. The H^(2/3) exponent belongs to other turbomachine-specific-speed conventions, not the standard centrifugal-pump form.
