# Industrial Specification: Nozzle Body/Shaft

## 1. Technical Definition
The structural core component of a vacuum nozzle that houses internal mechanisms and provides mounting/connection interfaces.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-1.5 bar absolute pressure differential, -40°C to 150°C temperature range**. Failure boundary: **Material yield strength threshold: 250 MPa for aluminum alloys, 450 MPa for stainless steel; Leak rate exceeding 1×10⁻⁹ mbar·L/s**, Mechanism: **Stress concentration at mounting interfaces exceeding material yield strength due to cyclic thermal expansion mismatch (Δα=23×10⁻⁶/°C for aluminum-stainless steel joints)**.

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

> **Primary Equation**: $\Delta P = f \cdot \frac{L}{D} \cdot \frac{\rho v^2}{2}$
