# Industrial Specification: Dispensing Nozzle/Valve

## 1. Technical Definition
A precision component that controls the flow, direction, and volume of material being dispensed in deposition or feeding systems.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-100 bar**. Failure boundary: **150 bar internal pressure differential**, Mechanism: **Yield strength of 316L stainless steel (205 MPa) exceeded at 150 bar pressure differential across 0.5 mm orifice diameter, causing permanent deformation and flow characteristic alteration**.

### 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.
