Convert fluid velocity to volumetric flow rate (GPM) for a specific pipe diameter. Useful for pump sizing and hydraulic system analysis.
For general water systems, 5 ft/s is a common maximum to prevent noise and pipe erosion. Suction lines should be lower (2-3 ft/s).
No, this is purely a geometric calculation relating area and velocity to volume. Pressure is needed to maintain that velocity, however.
Keep under 5fps.
