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 V̇).

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 m², with a velocity of 5.00 m/s. Calculate Flow Rate.
Given:
Area = 0.240 m²
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 m³/s
