), and the lengths of the converging and diverging sections (typically 3:1 and 4:1 ratios).

For engineers and designers, optimizing the is critical. Using an updated venturi scrubber design calculation XLS spreadsheet ensures efficiency, safety, and regulatory compliance. 1. Core Principles of Venturi Scrubber Design | Parameter | Formula | Typical Range /

If your process gas flow fluctuates, use the XLS sheet to evaluate performance at minimum flow rates. This data determines whether a variable-throat (adjustable damper blade) design is required to maintain constant pressure drop and efficiency.

A key part of your spreadsheet is balancing efficiency with energy costs. Use the : ΔP = (1.5 * vg² * ρg * t) / (dT) , where ΔP is in Pa, vg is throat gas velocity (m/s), ρg is gas density (kg/m³), t is throat length (m), and dT is throat diameter (m).
