Flow Rate Calculator

Find volumetric flow rate from area and velocity.

Pipe area

Flow velocity

Flow rate (m³/s) 0.02

Flow rate (L/min) 1,200

Formula: Q = area × velocity

Step-by-step with your numbers:

1. Values used:

2. Pipe area = 0.01

3. Flow velocity = 2

5. Flow rate = Pipe area x Flow velocity = 0.01 x 2 = 0.02m³/s

6. Flow rate = 1,200L/min

Did we solve your problem today?

Volumetric flow rate is cross-section area times fluid velocity.

The math behind it

Q = A × v. Multiply m³/s by 60,000 for L/min.

0.01 m² at 2 m/s → 0.02 m³/s (1,200 L/min).

Pipe velocity?

v = Q ÷ A — use the pipe velocity calculator.
