| Process | |
|---|---|
| Air, free convection | 2 - 15 |
| Air, forced convection | 30 - 200 |
| Water, free convection | 200 - 1.000 |
| Water, forced convection | 2.000 - 12.000 |
| Boiling | 2.000 - 60.000 |
| Condensation | 5.000 - 100.000 |
The heat transfer coefficient depends on the process and must be calculated!
