# Industrial Specification: Vacuum Manifold

## 1. Technical Definition
A distribution component that connects multiple vacuum ports to a central vacuum source in a vacuum table system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.001-1013 mbar absolute pressure**. Failure boundary: **Structural failure at 2.5 bar differential pressure or vacuum leak exceeding 1×10⁻⁶ mbar·L/s**, Mechanism: **Plastic deformation from differential pressure exceeding yield strength of aluminum alloy (typically 276 MPa for 6061-T6) or molecular flow leakage through micro-cracks exceeding 10 μm width**.

### 2.1 Analytical Physics Model
Governed by the **Thin-Wall Pressure Vessel Stress Analysis**:

> **Primary Equation**: $\sigma_h = \frac{P \cdot D}{2t}$  
> **Engineering Impact**: Determines the hoop stress boundary to prevent rupture.
