# Industrial Specification: Air Distribution Plenum

## 1. Technical Definition
A chamber designed to distribute air evenly within an Air Wash Separator system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.0 kPa differential pressure, 10-35°C air temperature, 0.5-3.0 m/s air velocity**. Failure boundary: **Structural collapse at 3.5 kPa differential pressure, material deformation at 50°C, resonance-induced fatigue at 8-12 Hz vibration frequency**, Mechanism: **Von Mises yield criterion exceeding 250 MPa stress concentration at mounting points, thermal expansion mismatch (α=23×10⁻⁶/°C aluminum vs α=12×10⁻⁶/°C steel), Helmholtz resonance at chamber natural frequency**.

### 2.1 Analytical Physics Model
Governed by the **Darcy-Weisbach Pressure Drop**:

> **Primary Equation**: $\Delta P = f \cdot \frac{L}{D} \cdot \frac{\rho v^2}{2}$  
> **Engineering Impact**: Critical for sizing CIP (Clean-In-Place) pump heads.
