. Use the following steps to calculate it based on a required collection efficiency:

Apply lists to ensure gas and liquid selections choose correct physical properties (e.g., Air, Water, Caustic Soda). venturi scrubber design calculation xls upd

Alternatively, the or Hesketh Equation can be programmed into adjacent columns to compare theoretical variations. Step 4: Johnstone Impaction Parameter (

– Rath Yatra, Monsoon arrival (street food safety, rainy day decor)

To build your design calculation spreadsheet, you must program several interconnected thermodynamic and fluid mechanics equations. Gas Velocity at the Throat ( The gas velocity at the throat typically ranges between Typically ranges from 7 to 20 gallons per 1,000 ACF

Program automatic lookups for gas density, water viscosity, and temperature corrections. Tab 3: Geometry & Sizing: Translate the calculated areas ( Atcap A sub t

): The most crucial calculation for energy consumption and performance. It often relies on empirical formulas such as the Calvert model:

Typical engineered throat velocities range between . Step 2: Liquid Droplet Size (Boll Correlation) The mean droplet diameter (

The size of the liquid droplets is critical, as smaller droplets capture particles more effectively. The is a widely used empirical formula for estimating the Sauter mean diameter (dl) of the droplets.
