# Industrial Specification: Hydraulic Power Unit

## 1. Technical Definition
A self-contained system that generates hydraulic power for operating machinery components.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **50-350 bar**. Failure boundary: **420 bar (burst pressure of SAE 100R2AT hose at 93°C)**, Mechanism: **Cavitation-induced erosion at vapor pressure threshold of 0.023 bar absolute (at 20°C hydraulic oil)**.

### 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.
