Copper Tubes - Heat Losses
Heat loss from uninsulated copper tubes vs. temperature differences between tube and air.
Values from the table below can be used to indicate the heat losses from uninsulated copper pipes:
| Nominal bore | Heat Loss | ||||||
|---|---|---|---|---|---|---|---|
| (W/m) | (Btu/hr ft) | ||||||
| Temperature difference (oC) | Temperature difference (oF) | ||||||
| (mm) | (inches) | 22 | 38 | 55 | 40 | 68 | 99 |
| 15 | 1/2 | 21 | 32 | 45 | 22 | 34 | 47 |
| 22 | 3/4 | 28 | 43 | 60 | 29 | 45 | 53 |
| 28 | 1 | 34 | 53 | 76 | 36 | 56 | 79 |
