Velocity
Convert kilometre per hour (km/h) to metre per second (m/s). Velocity is distance per unit time — the line-sizing quantity that flags erosion, noise, and pressure drop.
1 km/h = 0.2777778 m/s
To convert kilometre per hour to metre per second, multiply the km/h value by 0.2777778. To go the other way, divide by 0.2777778 (or multiply by 3.6).
| km/h | m/s |
|---|---|
| 1 | 0.2777778 |
| 2 | 0.5555556 |
| 5 | 1.388889 |
| 10 | 2.777778 |
| 25 | 6.944444 |
| 50 | 13.88889 |
| 100 | 27.77778 |
| 250 | 69.44444 |
| 500 | 138.8889 |
| 1000 | 277.7778 |
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 7.2 km/h is 2 m/s.
Multiply the value in km/h by 0.2777778 to get m/s. For example, 10 km/h = 2.777778 m/s.
1 km/h equals 0.2777778 m/s.
