Enter the cross-sectional area and the flow velocity into the calculator to determine the flow rate. This calculator helps in evaluating the flow rate of a fluid through a channel or pipe.

## Garrett Flow Formula

The following formula is used to calculate the Garrett flow rate.

Q = A * V

Variables:

- Q is the flow rate (cubic feet per second)
- A is the cross-sectional area through which the fluid flows (square feet)
- V is the flow velocity (feet per second)

To calculate the flow rate, multiply the cross-sectional area by the flow velocity.

## What is Garrett Flow?

Garrett flow refers to the volumetric flow rate of a fluid through a channel or pipe. It is a measure of how much fluid passes through a given cross-sectional area in a given amount of time. This calculation is essential in various engineering and environmental applications, such as water supply systems, sewage systems, and irrigation channels.

## How to Calculate Garrett Flow?

The following steps outline how to calculate the Garrett Flow.

- First, determine the cross-sectional area (A) through which the fluid flows in square feet.
- Next, determine the flow velocity (V) in feet per second.
- Use the formula from above = Q = A * V.
- Finally, calculate the flow rate (Q) in cubic feet per second.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem :**

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

cross-sectional area (A) = 2 square feet

flow velocity (V) = 3 feet per second
