Frequently Asked Questions

What does this calculator calculate?

The Firetube Boiler Flue Gas Velocity Calculator estimates Flue Gas Velocity based on the input parameters you provide

Why is flue gas mass flow rate important in this calculation?

flue gas mass flow rate is directly proportional to flue gas velocity. When you enter flue gas mass flow rate in kg/s, the calculator uses it in the engineering formula to compute the output

How should I interpret the result flue gas velocity?

The calculator outputs flue gas velocity in m/s. To convert to km/h, multiply the result by 3.6. The result is computed directly from the input values using the defined engineering formula

What units should I use for the inputs?

Enter each value in the units shown next to the input field: Flue Gas Mass Flow Rate (kg/s), Flue Gas Density (kg/m^3), Firetube Inner Diameter (m). Make sure all inputs use the specified units for consistent results

What assumptions does this calculator use?

This calculator uses automatically validated engineering formulas. Results are approximate and should be validated against site-specific conditions, applicable codes, and professional engineering judgment
