Enter the values of Velocity and Area in the respected boxes to find the pipe flow rate of a fluid by using flow rate calculator.

Table of Contents:

Flow Rate Calculator helps to calculate the flow rates of water and other fluids passing through a cross-sectional area. It uses the velocity of the fluid and the area of the place it passes through.

This pipe flow calculator can calculate:

- Flow Rate
- Flow Velocity
- Flow Area

Flow rate is defined as

**“**The volume of fluid each second that is passing through a cross-sectional slice of the pipe.**”**

The flow rate formula is

**Q = vA**

Where,

A = cross-sectional area of the pipe,

v = velocity

Let’s find out how to calculate flow rate manually.

*Example:*

Find the flow rate of a fluid through an area of **0.7 m ^{2}** flowing with a velocity of

** Solution**:

**Step 1: **Write down the values.

A = 0.7 m^{2}

V = 3 m/s

**Step 2: **Place the values in the flow rate formula

**Q = Av**

= 0.7 × 3

**Q = 2.1 m ^{3}/s**
