Velocity
Convert foot per second (ft/s) to foot per minute (ft/min). Velocity is distance per unit time — the line-sizing quantity that flags erosion, noise, and pressure drop.
1 ft/s = 60 ft/min
To convert foot per second to foot per minute, multiply the ft/s value by 60. To go the other way, divide by 60 (or multiply by 0.01666667).
| ft/s | ft/min |
|---|---|
| 1 | 60 |
| 2 | 120 |
| 5 | 300 |
| 10 | 600 |
| 25 | 1500 |
| 50 | 3000 |
| 100 | 6000 |
| 250 | 15000 |
| 500 | 30000 |
| 1000 | 60000 |
Line velocities are checked in m/s or ft/s against service-specific guidance bands.
High velocity means high friction loss and erosion risk; low velocity risks settling in slurry lines.
Worked example. A velocity of 6.56168 ft/s is 393.7008 ft/min.
Multiply the value in ft/s by 60 to get ft/min. For example, 10 ft/s = 600 ft/min.
1 ft/s equals 60 ft/min.
