# Industrial Specification: Fuel System

## 1. Technical Definition
A system that stores, filters, and delivers fuel to the engine for combustion in power generation applications.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **3.5-7.0 bar**. Failure boundary: **Fuel pressure below 2.1 bar or above 8.4 bar sustained for &gt;30 seconds**, Mechanism: **Cavitation-induced vapor lock at low pressure (below fuel vapor pressure of 0.7 bar at 40°C), or material yield stress exceedance at high pressure (ASTM A106 Grade B steel yield strength: 240 MPa)**.

### 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.
