Table 2
The parameters of ventilation duct and oxygen supply duct.
| | Duct diameter (m) | Volume airflow (m3/s) | Airflow velocity (m/s) |
| Forcing duct | D 1 = 0.50 | Q 1 = 1.0308 | = 5.25 | Exhausting duct | D 2 = 0.50 | Q 2 = 0.8246 | = 4.20 | Oxygen supply duct | D 3 = 0.05 | Q 3 = 0.0084 | = 4.20 |
