The flow velocity in corrugated metal hose should never exceed 150 ft./sec. for gas or 75 ft./sec. for liquids otherwise a resonant vibration can occur. Resonant vibration may cause very rapid failure of the assembly. Where the flow velocity exceeds these rates, an interlocked metal hose liner or larger hose I.D. is recomended.
To use Calculator just follow the steps listed below:
- Choose a Hose Series to Calculate Flow Velocity for;
- Select specific Hose within that series;
- Enter Flow Rate in CFM (Cubic Feet per Minute) and press “Calculate”.
- To convert Flow Rate from GPM (Gallons / Minute, gal/min) to CFM (Cubic Feet / Minute) enter Flow Rate in GPM press “Convert” button and then “Calculate”.
