Flue gas velocity
6.37 m/s
Cross-sectional area
0.785 m²
Volumetric flow rate
5 m³/s
Hourly flow
18,000 m³/hr
Formula and working
V (m/s) = Q (m³/s) ÷ A; A = π × (D/2)²
- 1
Collect the inputs
Volumetric flow rate = 5 m³/s; Stack diameter = 1 m
- 2
Apply the formula
V (m/s) = Q (m³/s) ÷ A; A = π × (D/2)²
- 3
Result
Flue gas velocity = 6.37 m/s
