# Industrial Specification: Spray Nozzle

## 1. Technical Definition
A precision component that atomizes and directs liquid into a controlled spray pattern.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **2.0-15.0 bar (29-218 psi)**. Failure boundary: **18.0 bar (261 psi) internal pressure causing permanent orifice deformation**, Mechanism: **Plastic deformation of nozzle orifice due to yield strength exceedance (316L stainless steel: 170 MPa yield strength)**.

### 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 &gt; 25 μm in fluid stream | 8 | Orifice clogging causing flow reduction &gt; 40% from nominal | Install 10 μm absolute filtration upstream with differential pressure monitoring |
| Cavitation at vapor pressure &lt; 0.023 bar absolute (water at 20°C) | 8 | Surface erosion causing spray pattern distortion &gt; 15° from nominal | Maintain NPSHa &gt; NPSHr + 1.5 bar margin with pressure regulation |

### Industrial DNA Context (De-duplicated)
**Complementary Dependencies**: **High-Pressure Pump System**, **Liquid Filtration Unit**, **Spray Pattern Testing Fixture**  
**Downstream Applications**: Agricultural Sprayers, Industrial Cleaning Systems, Fire Suppression Equipment  

## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are best for corrosive chemical applications in spray nozzles?
**A**: For corrosive environments, ceramic or PTFE plastic spray nozzles offer superior chemical resistance compared to metals like stainless steel or brass.

### Q: How does the swirl chamber affect spray pattern in industrial nozzles?
**A**: The swirl chamber creates centrifugal force that atomizes liquid into a fine, uniform spray pattern. Different insert designs produce hollow cone, full cone, or flat fan patterns for specific machinery applications.

### Q: Why include a filter in spray nozzle assemblies for equipment manufacturing?
**A**: Filters prevent orifice clogging from particulates in liquid systems, maintaining consistent spray performance and extending nozzle lifespan in industrial machinery.

## 6. Manufacturing Compliance
- ISO 9001:2015 (QUALITY MANAGEMENT SYSTEMS)
