The approximate numerical range of heat transfer coefficient on the convective heat transfer surface.
| Process | |
| Natural convection | | Air | 1∼10 | Water | 200–1000 |
| Forced convection | | Gas | 20–100 | High pressure vapor | 500–35000 | Water | 1000–1500 |
| Heat transfer with phase change of water | | Boiling | 2500–3500 | Vapor condensation | 5000–25000 |
