Engineering ToolBox > Pumping Boiling Liquids - Delivery Flow Velocities
As a rule of thumb the following velocities can be used in design of piping and pumping systems for boiling liquids:
| Pipe Dimensions | Boiling Liquids | ||
| inches | mm | m/s | ft/s |
| 1 | 25 | 1 | 3.5 |
| 2 | 50 | 1.1 | 3.6 |
| 3 | 75 | 1.15 | 3.8 |
| 4 | 100 | 1.25 | 4 |
| 6 | 150 | 1.5 | 4.7 |
| 8 | 200 | 1.75 | 5.5 |
| 10 | 250 | 2 | 6.5 |
| 12 | 300 | 2 | 6.5 |
