Centrifugal pumps are widely used in various industries to transport fluids by converting mechanical energy into hydraulic energy. In order to properly size and select a centrifugal pump for a specific application, it is essential to perform hydraulic calculations to determine the pump's hydraulic and shaft power requirements. The ideal hydraulic power to drive a pump depends on whether it is the static lift from one height to another or the total head loss component of the system. By understanding the hydraulic calculations involved, engineers and designers can optimize pump performance and efficiency.

Calculating Hydraulic Power
The hydraulic power required to drive a centrifugal pump can be calculated using the following formula:
\[ P_{hyd} = \frac{Q \times \rho \times g \times H_{total}}{1000 \times \eta} \]
Where:
- \( P_{hyd} \) = Hydraulic power (kW)
- \( Q \) = Flow rate (m³/s)
- \( \rho \) = Density of the fluid (kg/m³)
- \( g \) = Acceleration due to gravity (9.81 m/s²)
- \( H_{total} \) = Total head loss in the system (m)
- \( \eta \) = Pump efficiency
Shaft Power Calculation
The shaft power required by the pump can be determined by considering the pump efficiency:
\[ P_{shaft} = \frac{P_{hyd}}{\eta} \]
Where:
- \( P_{shaft} \) = Shaft power (kW)
Centrifugal Pump Sizing and Selection
When sizing a centrifugal pump, it is crucial to consider factors such as the flow rate, total head loss, fluid properties, and system requirements. A centrifugal pump size chart can be used to determine the appropriate pump size based on the desired flow rate and head requirements. By selecting the right pump size, engineers can ensure optimal performance and energy efficiency.
Pump Design Considerations
Centrifugal pump design calculations play a significant role in determining the pump's performance characteristics. Factors such as impeller diameter, speed, and efficiency are crucial in designing a pump that meets the system requirements. Centrifugal pump design calculations pdf resources provide detailed guidelines on designing efficient and reliable pumps for various applications.
Discharge Formula and Flow Rate Calculation
The discharge formula for a centrifugal pump is given by:
\[ Q = \frac{A \times V}{1000} \]
Where:
- \( Q \) = Flow rate (m³/s)
- \( A \) = Area of the pipe (m²)
- \( V \) = Velocity of the fluid (m/s)
Centrifugal pump flow rate calculator tools are available to simplify the calculation of flow rates based on the pump's design parameters and system requirements.
Remember, Centrifugal pump produce Liquid Head not the pressure. HOW MUCH HEAD? The head produced by a centrifugal pump is proportional to the velocity attained by the fluid as it …
Useful information on NPSH What is NPSH? NPSH stands for Net Positive Suction Head and is a measure of the pressure experienced by a fluid on the suction side of a centrifugal pump. It is quoted as a Head (in feet or metres) rather than as an actual pressure (lb/in 2, psi or Pa) because ‘head’ is a fluid-independent property: a pump will lift different fluids to the same height .
