# Industrial Specification: Spray System

## 1. Technical Definition
A precision fluid delivery subsystem that atomizes and applies coating solutions onto pharmaceutical tablets within an automated coating system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.8-3.2 bar (12-46 psi) at nozzle exit, 15-35°C fluid temperature, 0.5-2.0 m/s traverse speed**. Failure boundary: **Nozzle pressure drop below 0.6 bar causes droplet size &gt;150 μm (coating uniformity failure), fluid viscosity &gt;50 cP causes flow rate deviation &gt;15%**, Mechanism: **Rayleigh-Plateau instability threshold exceeded at Weber number &lt;4 causes ligament formation instead of atomization; Hagen-Poiseuille law deviation at Reynolds number &lt;500 causes laminar flow disruption**.

### 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 |
| :--- | :--- | :--- | :--- |
| Piezoelectric actuator crystal depolarization due to 85°C thermal exposure | 8 | Nozzle oscillation frequency drops from 120 kHz to &lt;80 kHz, causing droplet size increase from 30 μm to &gt;100 μm | PZT-5H ceramic with Curie temperature 350°C and integrated thermoelectric cooler maintaining &lt;60°C |
| 316L stainless steel nozzle erosion at fluid velocity &gt;25 m/s with 5% abrasive particle content | 8 | Orifice diameter increases from 100 μm to &gt;130 μm within 200 operating hours, causing flow rate increase from 50 mL/min to &gt;75 mL/min | Tungsten carbide nozzle insert with Vickers hardness 1600 HV and 5 μm filtration upstream |
