To size a pump, you must define: The flow rate of liquid the pump is required to deliver The total differential head the pump must generate to deliver the required flow rate This is the case for all types of pumps: centrifugal or positive displacement. Other key .
Centrifugal pumps are widely used in various industries for fluid transportation and are known for their efficiency and reliability. In this article, we will explore a centrifugal pump example to understand how these pumps work and how to calculate important parameters.
The document contains 5 solved problems related to centrifugal pumps. The problems cover topics like calculating head, power required, efficiency,
Example:
A centrifugal pump has an outlet diameter equal to two times the inner diameter and is running at 1200 rpm. The pump works against a total head of 75 m. We need to calculate the velocity of flow through the impeller.
Solution:
To calculate the velocity of flow through the impeller, we can use the formula:
\[ V = \frac{Q}{A} \]
Where:
- \( V \) = Velocity of flow (m/s)
- \( Q \) = Flow rate (m\(^3\)/s)
- \( A \) = Area of the impeller (m\(^2\))
First, we need to calculate the flow rate using the formula:
\[ Q = \frac{\pi \times D^2 \times N}{4 \times 60} \]
Where:
- \( D \) = Diameter of the impeller (m)
- \( N \) = Pump speed (rpm)
Given that the outlet diameter is two times the inner diameter, we can calculate the diameter of the impeller:
Inner diameter, \( D_i = D \)
Outlet diameter, \( D_o = 2D \)
Area of the impeller, \( A = \frac{\pi}{4} \times (D_o^2 - D_i^2) \)
Substitute the values and calculate the flow rate:
\[ Q = \frac{\pi \times (2D)^2 \times 1200}{4 \times 60} \]
Next, we calculate the area of the impeller:
\[ A = \frac{\pi}{4} \times ((2D)^2 - D^2) \]
Now, we can calculate the velocity of flow using the formula mentioned earlier.

Axial Pump vs. Centrifugal Pump What's the Difference? Axial pumps and centrifugal pumps are both types of dynamic pumps used to move fluids. However, they differ in their design and operation. Axial pumps have a rotating impeller that pushes the fluid in an axial direction, parallel to the pump shaft. This design allows for high flow rates and .
