Pump Classification based on flow direction through impeller:
Radial flow pump: The liquid enters the impeller axially, and head is developed by centrifugal force. The liquid leaves the impeller radially. Such pumps are called radial flow pumps.
Axial flow pump: In this, the head is developed by the propelling action of vanes. The liquid enters the impeller axially and also leaves axially. These pumps have very large discharges but low heads.
Mixed flow pump: Flow through a mixed flow impeller is a combination of axial and radial flow. The head is developed by the combined action of centrifugal force and propelling action of the impeller. The flow enters axially, not necessarily in the centre, but leaving at some angle between radially and axially.

In an axial flow pump, the liquid enters and leaves the impeller axially.
Axial flow pumps are a type of centrifugal pump that is specifically designed to handle large volumes of liquid with relatively low head (pressure) requirements. They are commonly used in applications such as irrigation, drainage, and wastewater treatment.
Explanation:
1. Introduction to axial flow pumps:
- Axial flow pumps are designed to move fluid axially, parallel to the impeller shaft.
- They consist of a rotating impeller with curved blades that create a pressure gradient and propel the fluid in the axial direction.
- The impeller is housed within a casing, which helps to guide the flow of fluid through the pump.
2. Direction of fluid flow:
- In an axial flow pump, the fluid enters and leaves the impeller axially, meaning it flows in the same direction as the impeller shaft.
- This is in contrast to radial flow pumps, where the fluid enters and leaves the impeller radially, perpendicular to the impeller shaft.
3. Impeller design:
- The impeller of an axial flow pump is specifically designed to create a low-pressure region at the center and a high-pressure region at the periphery.
- As the impeller rotates, the curved blades push the fluid from the center to the periphery, generating a continuous flow of fluid in the axial direction.
4. Benefits of axial flow pumps:
- Axial flow pumps are known for their high flow capacity, making them suitable for applications that require the movement of large volumes of fluid.
- They are also energy-efficient, as they can achieve high flow rates with relatively low power consumption.
- Additionally, axial flow pumps have a compact design and can be installed vertically or horizontally, depending on the application requirements.
Conclusion:
In conclusion, the correct answer is option D, which states that in an axial flow pump, the liquid enters and leaves the impeller axially. This is because axial flow pumps are specifically designed to move fluid in the axial direction parallel to the impeller shaft.
