Insulated Copper Tubes - Heat Loss
Heat loss to surrounding air from insulated copper tubes.
The heat loss from insulated copper pipes or tubes to surrounding air are indicated below. The heat loss is based on temperature difference 55 oC (99 oF) with insulation thickness 25 mm (1 inch) and conductivity coefficient k = 0.043 W/m oC (0.3 Btu in/ft2hr oF).
| Nominal bore | Heat Loss | ||
|---|---|---|---|
| (mm) | (inches) | (W/m) | (Btu/hr ft) |
| 22 | 3/4 | 8 | 8 |
| 28 | 1 | 10 | 10 |
| 42 | 1 1/2 | 11.5 | 12 |
| 54 | 2 | 14.5 | 15 |
| 67 | 2 1/2 | 16 | 17 |
| 76 | 3 | 19 | 20 |
- 1 W = 3.4 Btu/hr
- 1 ft (foot) = 0.3048 m
