Typically ranges from 60 to 150 m/s. Higher velocities increase efficiency but also increase pressure drop and energy costs. Throat Area ( cap A sub t Calculated as Critical Dimensions: Throat Length ( cap L sub t Often taken as 3 times the throat diameter ( cap D sub t Diverging Section Length ( cap L sub d
) : A primary driver for collection efficiency, usually ranging from 7 to 20 gallons per 1000 cubic feet of gas. Mean Droplet Diameter (
Function VenturiEfficiency(Particle_Diameter_Micron As Double, LG_Ratio As Double, V_Throat_FtSec As Double, Gas_Density As Double, Liquid_Density As Double) As Double ' Simplified efficiency calculation based on Johnstone Equation ' Returns efficiency as a percentage (0-100)
Typically expressed in gallons per 1,000 cubic feet of gas. venturi scrubber design calculation xls upd
Key goals
Venturi scrubbers are highly effective wet scrubbing systems used primarily to remove fine particulate matter (PM) from industrial gas streams

To build an interactive dashboard for rapid engineering iterations, organize your Excel workbook into four clean, color-coded tabs: Tab 1: Project Readme & Revision Control
To design an effective Venturi scrubber calculation in Excel, you must structure your spreadsheet to handle input parameters, intermediate calculations for throat velocity, and final outputs for pressure drop and collection efficiency. If you share with third parties, their policies apply
