# Industrial Specification: Spray Headers and Nozzles

## 1. Technical Definition
A distribution and atomization assembly that delivers and disperses cooling fluid within an integrated cooling system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **3.5-20.0 bar (50-290 psi) at 15-85°C fluid temperature**. Failure boundary: **Cracking at 25.5 bar (370 psi) internal pressure or 120°C fluid temperature**, Mechanism: **Cavitation-induced erosion at vapor pressure threshold (0.023 bar at 20°C) and thermal stress from differential expansion (stainless steel α=17.3×10⁻⁶/°C vs brass α=19×10⁻⁶/°C)**.

### 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.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| f | Friction Factor | Engineering Constant |
| L | Pipe Length | Engineering Constant |
| v | Velocity | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Particulate contamination exceeding 25 μm in cooling fluid | 8 | Nozzle orifice erosion increasing diameter by &gt;15% from nominal 0.8 mm | Install 10 μm absolute filtration with differential pressure monitoring at 0.5 bar threshold |
| Water hammer from rapid valve closure within 0.2 seconds | 8 | Header weld seam fatigue cracking at stress concentration factor Kt=3.2 locations | Implement controlled ramp valve closure (minimum 2.0 seconds) with accumulator installation at header inlet |
