) changes rapidly. Program the automated transition formula rather than relying on manual lookup tables:
📥 Drop a “Venturi” in the comments or DM me, and I’ll send you the read-only link (no email required – direct download).
The pressure drop is a critical performance indicator, as it directly relates to the energy required to operate the scrubber. Hesketh Equation : Commonly used to estimate cap delta cap P (in Pascals):

For decades, engineers have relied on manual calculations, nomographs, and basic spreadsheets. But with tighter environmental regulations (e.g., EPA MACT standards, EU BREF documents) and the need for energy optimization, the demand for an has skyrocketed. This article provides a deep dive into the core calculations, the latest updates in modeling approaches, and how to leverage modern spreadsheets to design high-performance systems. venturi scrubber design calculation xls upd
The gas velocity increases, accelerating to high speeds ( ) as the cross-section narrows.

Proper sizing ensures the gas reaches the necessary velocity to atomize the liquid. Venturi Scrubber Design Calculations | PDF | Gases - Scribd ) changes rapidly
High gas velocity in the throat (100–300 ft/s or 30–90 m/s) is crucial for atomizing the scrubbing liquid.
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.
Suspended solids in the scrubbing liquid can erode the throat.
To facilitate the design calculation process, XLS (Excel) can be used to create a spreadsheet that automates the calculations. The following steps outline the general procedure for performing venturi scrubber design calculations using XLS: Hesketh Equation : Commonly used to estimate cap
