Frequently Asked Questions
Common questions about Pipe Flow Rate Calculator, formulas, and expected usage.
What formula is used for pipe flow rate?
Flow is calculated as Q = A × v, where A is pipe cross-sectional area and v is flow velocity.
How do you convert cfs to gpm?
Multiply cubic feet per second by 448.831 to get gallons per minute.
Can I use nominal pipe size as inside diameter?
For better accuracy, use actual inside diameter. Nominal size and wall thickness vary by material and schedule.
What velocity range is typical in plumbing systems?
Many domestic systems target moderate velocities to limit noise and pressure loss, often around 2 to 8 ft/s depending on application.
