Enter your flow rate, head, and pipe diameter into the calculator to determine your pump power.

## Pump Power Calculation Formula

The following formula is used to calculate the pump power from your flow rate, head, and pipe diameter.

Pump Power = (Flow Rate * Head * Pipe Diameter) / 1000

Variables:

- Pump Power is the power required to pump the fluid (kW)
- Flow Rate is the volume of fluid flowing per minute (L/min)
- Head is the height to which the fluid is to be pumped (m)
- Pipe Diameter is the diameter of the pipe (mm)

To calculate the pump power, multiply the flow rate by the head and the pipe diameter, then divide the result by 1000.

## What is Pump Power Calculation?

Pump power calculation refers to the process of determining the power required to pump a specific fluid at a given flow rate and head through a certain pipe diameter. This involves understanding the characteristics of the fluid, the height to which it needs to be pumped, and the volume of fluid being moved. Accurate pump power calculation is essential for selecting the right pump for your system and ensuring efficient operation.

## How to Calculate Pump Power?

The following steps outline how to calculate the pump power using the given formula.

- First, determine your flow rate, head, and pipe diameter.
- Next, use the formula: Pump Power = (Flow Rate * Head * Pipe Diameter) / 1000.
- Plug in the values to calculate the pump power.
- Finally, check your answer with the calculator above.

**Example Problem:**

Use the following variables as an example problem to test your knowledge.

Head = 20 m

Pipe Diameter = 50 mm

## FAQ

**1. What is flow rate?**

Flow rate is the volume of fluid that flows through a pipe or channel per unit time, typically measured in liters per minute (L/min).

**2. How is head defined in pump calculations?**

Head refers to the height to which the fluid is to be pumped, typically measured in meters (m). It represents the energy required to move the fluid to a specific elevation.

**3. How often should I use the pump size calculator?**

It’s helpful to use the pump size calculator whenever there’s a change in your system requirements, such as changes in flow rate, head, or pipe diameter, or if you’re considering upgrading your pump system.

**4. Can this calculator be used for different fluids?**

Yes, you can adjust the fluid type and properties in the advanced calculator to match the characteristics of different fluids to calculate the pump power accordingly.

**5. Is the calculator accurate?**

The calculator provides an estimate of the pump power based on the inputs provided. For exact figures, it’s best to consult with a pump specialist or refer to detailed engineering data.
