# Industrial Specification: Air Register

## 1. Technical Definition
A device that regulates and controls the flow of air into a burner system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.0 bar differential pressure, 0-100% opening angle, -40°C to 250°C ambient temperature**. Failure boundary: **Mechanical failure at 3.5 bar differential pressure, thermal failure at 300°C ambient temperature, actuator failure at 85% duty cycle continuous operation**, Mechanism: **Mechanical fatigue from cyclic pressure loading (S-N curve with 10^6 cycles at 2.5 bar), thermal expansion mismatch between stainless steel (17.3 μm/m·K) and aluminum (23.1 μm/m·K) components, bearing seizure from lubricant degradation at Arrhenius rate constant k=1.2×10^-3 s^-1 at 250°C**.

### 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.
