Water Supply Pipe Lines - Sizing
A water supply pipe line should be sized according expected demand and not the total theoretical demand from all fixtures at the same time. Due to intermittent use of the fixtures it may be difficult to predict a realistic demand but the values below are relevant for water supply lines in applications like homes, offices, nursing homes etc.
| Copper Pipe Size DN (mm) | Total Maximum Theoretical Demand Summarized (liter/s) | Maximum Expected Demand (liter/s) |
|---|---|---|
| 12 | 0.2 | 0.2 |
| 15 | 0.8 | 0.4 |
| 18 | 1.6 | 0.5 |
| 22 | 4.0 | 0.6 |
| 28 | 15 | 1.1 |
| 35 | 30 | 1.8 |
| 42 | 65 | 2.8 |
| 54 | 130 | 4.5 |
