Frequently Asked Questions (FAQ)
What is the Pipe Flow Rate & Fluid Velocity Calculator (Q = A v) and how does it work?
Hydraulic engineering and fluid mechanics tool. Computes liquid volume transported per unit time based on internal pipe diameter.
How do I use this Pipe Flow Rate & Fluid Velocity Calculator (Q = A v)?
Enter Internal Pipe Diameter ($d$ in millimeters - mm). Enter Fluid Velocity ($v$ in m/s, recommended 1.0 to 2.5 m/s for water). View Calculated Volumetric Flow Rate in Liters per second (L/s), m³/h, and GPM.
What mathematical formula is used in this calculation?
Area A = (π * d²) / 4. Flow Rate Q = A * v (in m³/s). 1 m³/s = 1000 L/s.
