Flow Rate vs Inside Diameter
Fórmula
## Pipe Flow Rate **Q = A x V** Where A is the cross-sectional area of the pipe (pi x r squared) and V is the average fluid velocity. Convert inches to feet before computing the area. Multiply cu ft/s by 448.831 to get gallons per minute.
Ejemplo Resuelto
A 2-inch inside-diameter pipe with water flowing at 5 ft/s.
- 01Radius in feet = 2 / 2 / 12 = 0.0833 ft
- 02Area = pi x 0.0833 squared = 0.02182 sq ft
- 03Q = 0.02182 x 5 = 0.1091 cu ft/s
- 04GPM = 0.1091 x 448.831 = 48.95 GPM
Preguntas Frecuentes
What is a typical residential water velocity?
Most plumbing codes recommend keeping velocity between 4 and 8 ft/s for supply lines. Higher velocities cause noise and accelerated pipe wear.
Does this formula work for any fluid?
Yes, the continuity equation Q = A x V applies to any incompressible fluid. The velocity you enter should reflect actual flow conditions.
