Air Pollution Control - Stacks
Solving for average wind speed for neutral stability conditions.
Inputs:
Conversions:
| stack gas exit speed (Vs) | = | 0 | | = | 0 | meter/second |
| stack diameter (d) | = | 0 | | = | 0 | meter |
| stack heat emission rate (Qh) | = | 0 | | = | 0 | kilojoule/second |
| plume rise (Δh) | = | 0 | | = | 0 | meter |
Solution:
| average wind speed (u) | = | HAS NOT BEEN CALCULATED | |
