Frequently Asked Questions

What does this calculator calculate?

The Zhang et al. (2001) PM2.5 Dry Deposition Velocity Calculator estimates Dry deposition velocity based on the input parameters you provide

Why is aerodynamic resistance important in this calculation?

aerodynamic resistance is inversely proportional to dry deposition velocity. When you enter aerodynamic resistance in s/m, the calculator uses it in the engineering formula to compute the output

How should I interpret the result dry deposition velocity?

The calculator outputs dry deposition 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: Aerodynamic resistance (s/m), Quasi-laminar boundary layer resistance (s/m), Canopy resistance (s/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
