# Industrial Specification: Vacuum Pump

## 1. Technical Definition
A mechanical device that removes gas molecules from a sealed volume to create a partial vacuum within an industrial system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **1e-3 to 1013 mbar absolute pressure**. Failure boundary: **Ultimate pressure &gt; 1e-2 mbar for rotary vane pumps, &gt; 1e-6 mbar for turbomolecular pumps**, Mechanism: **Vapor pressure of pump fluid exceeding system pressure (rotary vane), blade-tip speed &lt; 400 m/s causing insufficient momentum transfer (turbomolecular)**.

### 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.
