Where ψ (Stokes number) = (ρp × dp² × v_t) / (9 × μg × D_drop)
Before diving into the spreadsheet cells, it is vital to understand the variables at play. A Venturi scrubber operates on Bernoulli’s principle. The gas stream enters a converging section, accelerates to high velocities (often 100–400 ft/s) in the throat, and then expands in a diverging section. venturi scrubber design calculation xls
Where:
Column A: v_t guess Column B: L/G ratio (0.4 to 2.0 L/m³ typical) Column C: ΔP using Calvert’s formula Column D: Compare to allowable ΔP. Where ψ (Stokes number) = (ρp × dp²
To create a functioning spreadsheet, organize your Excel work into three distinct areas: Gas Volumetric Flow Rate ( Qgcap Q sub g Gas Density ( ρgrho sub g ) and Viscosity ( μgmu sub g Gas Temperature ( Liquid Flow Rate ( Qlcap Q sub l Particle Density ( ρprho sub p ) and Mean Particle Diameter ( Target Efficiency ( Calculation Area: Where: Column A: v_t guess Column B: L/G ratio (0
