Velocity Calculator

To use the calculator, please view this page on a desktop computer or on "Desktop Mode" if using a mobile device.

Flow velocity in metal hose should never exceed 150 ft/sec for gas or 75 ft/sec for liquids or else resonant vibration can occur. This may cause rapid failure of the assembly.

Where flow velocity exceeds these rates, an interlocked hose liner or larger hose I.D. is recommended. Please contact us for design considerations.

Note on Using the Calculator

Flow rate needs to be in cubic feet per minute (ft3/min) for calculator to work properly. If flow rate is known in gallons per minute (gal/min), input flow rate and click “Convert” before hitting “Calculate.”
