# Industrial Specification: Dispense Pump/Valve

## 1. Technical Definition
A precision fluid control component that meters and directs coating materials in dispensing systems.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-100 bar at 0.01 bar resolution, 5-60°C fluid temperature, 0.1-1000 cP viscosity**. Failure boundary: **Seal failure at 120 bar differential pressure, actuator burnout at 85°C ambient temperature, cavitation onset at 0.3 bar vapor pressure margin**, Mechanism: **Cavitation-induced erosion at NPSHa &lt; NPSHr + 0.3 bar, elastomer seal degradation via Arrhenius kinetics (Ea=80 kJ/mol) above 60°C, piezoelectric actuator depolarization at Curie temperature (350°C) proximity**.

### 2.1 Analytical Physics Model
Governed by the **Darcy-Weisbach Pressure Drop**:

> **Primary Equation**: $\Delta P = f \cdot \frac{L}{D} \cdot \frac{\rho v^2}{2}$
