A necessary precaution in selection of pumps for parallel operations is that:
- A. H-Q characteristics of both should be identical
- B. Both pumps should be centrifugal type
- C. Both pumps should be identical
- D. There should not be change from positive to negative slope in H-Q curve
Answer: A. H-Q characteristics of both should be identical
Explanation: For stable parallel operation, pumps should have matching Head-Discharge (H-Q) characteristics to ensure load sharing and prevent one pump from overpowering the other.
