# Industrial Specification: Vent Housing

## 1. Technical Definition
The protective enclosure that houses and supports the internal components of a safety vent system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-15 bar differential pressure**. Failure boundary: **18 bar differential pressure or 150°C continuous temperature**, Mechanism: **Plastic deformation due to hoop stress exceeding yield strength (σ_y = 250 MPa for 316L stainless steel) at 18 bar, or polymer degradation at 150°C for polypropylene housings**.

### 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.
