Venturi scrubbers and differential flow nozzles utilize converging geometric cones to accelerate incoming process gas streams, creating localized pressure drops that atomize scrubbing liquor and capture micron-sized particulate matter. This engineering tool provides a three-variable proportional estimator for evaluating cross-sectional duct constrictions, dynamic flow velocity factors, and nozzle throat performance metrics.

### Fluid Nozzle Dynamics & Ratio Estimator

Instead of performing step-wise compressible gas integration or empirical wet-wall droplet collection calculations, the tool determines proportional aerodynamic sizing parameters from three key values: - **Upstream Duct Metric (`val1`, default 100):** Incoming duct cross-sectional area index or volumetric gas throughput. - **Dynamic Velocity Multiplier (`val2`, default 20):** Operational velocity acceleration factor across the convergent cone. - **Constriction Divisor (`val3`, default 5):** Throat area reduction ratio or boundary layer safety allowance.

Derived mathematical outputs produced instantaneously: 1. **Throat Acceleration Factor:** $$\text{Velocity Metric} = \frac{\text{val1} \times \text{val2}}{\max(0.01, \text{val3})}$$ 2. **Hydrodynamic Root Dimension:** $$\text{Root Index} = \sqrt{\max(0, \text{val1} \times \text{val2})}$$ 3. **Inlet-to-Throat Velocity Distribution:** $$\text{Proportional Ratio} = \left(\frac{\text{val1}}{\text{val1} + \text{val2}}\right) \times 100\%$$

### Worked Industrial Scrubber Example

Sizing an emission control scrubber on an industrial boiler exhaust: - **Inlet Volume Metric (`val1`):** 160 - **Flow Acceleration Coefficient (`val2`):** 30 - **Throat Reduction Divisor (`val3`):** 4 - **Throat Velocity Factor:** $(160 \times 30) / 4 = 4800 / 4 = \mathbf{1200.00}$ - **Geometric Flow Root:** $\sqrt{160 \times 30} = \sqrt{4800} \approx \mathbf{69.28}$ - **Distribution Percentage:** $[160 / (160 + 30)] \times 100\% = (160 / 190) \times 100\% \approx \mathbf{84.21\%}$
