Meters per second to cubic meters per hour
Type a value in m/s to get it in m³/h instantly.
That's 2× as fast as the erosive limit — nothing on our list beats it. Getting water moving that fast costs about 5,099 mm of head.
Convert the other way: m³/h to m/s
What it means
How fast is it moving?
Velocities are averages across the bore. At the wall the fluid is stationary and in the middle it moves faster, which is what erodes bends.
The math
How to convert m/s to m³/h
Velocity is flow divided by cross-sectional area: v = Q ÷ (π × (bore ÷ 2)²). Because the area goes with the square of the bore, one size up cuts the velocity to less than half. The figures below use the bore selected above.
Example: 10 m/s = 7.32899 m³/h.
The table below is for DN15, ½ inch (16.1 mm bore).
