# Industrial Specification: Proportioning Dosing Unit

## 1. Technical Definition
A precision component that accurately measures and dispenses specific quantities of beverage ingredients according to predetermined ratios.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-5.0 bar (10-500 kPa) differential pressure across dosing valve**. Failure boundary: **Dosing accuracy deviation exceeding ±0.5% of setpoint or flow rate below 85% of nominal capacity**, Mechanism: **Wear-induced clearance increase in metering piston-cylinder assembly beyond 15 μm tolerance, causing laminar flow disruption and volumetric inefficiency per Hagen-Poiseuille law**.

### 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 |
