Answer
Correct Answer: Axial flow pump (propeller type)
Explanation
Concept/Approach
- Flood control and irrigation often require very high discharge at low to moderate head.
- Axial (propeller) pumps provide the highest flow rates at low heads with compact structures, making them ideal for these applications.
