# How To Calculate Flow Rate?

Short tutorial on how to calculate flow rate of a pipe with a neat example and formula.

## Calculate Pipe Flow Rate

In Engineering Physics, Flow Rate is the volume of fluid which passes per unit time. The volumetric flow rate is usually represented by the symbol Q (sometimes VÌ‡).

**Formula:**

**Flow Rate of a Pipe Q = Area x Velocity**

Let us learn here how to calculate flow rate of a pipe with a neat example.

**Example: **Consider that the area of the water as it flows through the pipe is 0.240 m^{2}, with a velocity of 5.00 m/s. Calculate Flow Rate.

**Given:**

Area = 0.240 m^{2}

Velocity = 5 m/s

**Solution:**

Applying the values in the **flow rate of a pipe formula**, we get,

Pipe Flow Rate Q = Area x Velocity

Pipe Flow Rate Q = 0.240 x 5

Pipe Flow Rate Q = 1.20 m^{3}/s
