Flow Velocity From Volumetric Flow

Given a volumetric flow rate and a circular pipe diameter, calculate the average flow velocity at that cross-section using the relationship between volumetric flow rate, cross-sectional area, and velocity.

✓ All 2 test cases pass.

Inputs

Volumetric flow rate

Volumetric flow rate in m³/s

Pipe diameter

Pipe diameter in m
