# Industrial Specification: Orifice / Nozzle

## 1. Technical Definition
A precision component that controls and directs fluid flow through an injection valve.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-350 bar differential pressure, 0.1-50 L/min flow rate, -40°C to 150°C temperature**. Failure boundary: **Cavitation inception at vapor pressure ≤ 0.023 bar absolute, erosion failure at flow velocity &gt; 45 m/s, thermal stress cracking at ΔT &gt; 80°C**, Mechanism: **Cavitation-induced erosion from localized pressure drop below fluid vapor pressure (Bernoulli principle), thermal fatigue from cyclic temperature gradients exceeding material yield strength, abrasive wear from particle impingement at high velocity**.

### 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.

### Q: What are the main applications of orifice/nozzle components in machinery manufacturing?
**A**: Orifice/nozzle components are critical for precise fluid control in injection systems, used in hydraulic machinery, fuel injection systems, lubrication systems, and industrial spray applications where accurate flow regulation is essential.

### Q: How do material choices (stainless steel, tungsten carbide, ceramic) affect orifice/nozzle performance?
**A**: Stainless steel offers corrosion resistance and durability for general applications, tungsten carbide provides extreme wear resistance for abrasive fluids, while ceramic offers superior chemical resistance and thermal stability for high-temperature or corrosive environments.

### Q: What specifications should be considered when selecting orifice/nozzle components?
**A**: Key specifications include orifice diameter (for flow rate control), pressure rating, temperature range, material compatibility with fluids, surface finish requirements, and connection type to ensure proper integration with injection valve systems.
