Cooling Towers
- Relative cooling tower size is sensitive to the difference between the exit and wet bulb temperatures (see the table):
| Temperature Differential °F | 5 |
15 | 25 |
| Relative Volume | 2.4 |
1.0 | 0.55 |
- In commercial units, 90% saturation of the air is feasible.
- Tower fill has a highly open structure to minimise pressure drop, which, typically, is a maximum of 2 in. in H2O.
- Water in contact with air under adiabatic conditions eventually cools to the wet-bulb temperature.
