Pump selection for flood control and irrigation (large discharge, low head) Among the listed pumps, identify the most suitable type for moving very large flows against small heads. Choose the correct pump type.

Difficulty: Easy

Centrifugal pump (radial flow)
Axial flow pump (propeller type)
Mixed flow pump
Reciprocating pump

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.

Final Answer
Axial flow pump (propeller type)
