# Industrial Specification: Air Blower

## 1. Technical Definition
A mechanical device that supplies combustion air to a burner assembly.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.0 bar differential pressure, 15-35°C inlet air temperature, 0.8-1.2 kg/m³ air density**. Failure boundary: **Impeller tip speed exceeding 180 m/s (Mach 0.53), bearing temperature exceeding 120°C, shaft deflection exceeding 0.1 mm**, Mechanism: **Centrifugal force-induced impeller yield stress exceedance at 180 m/s tip speed (σ_yield = 250 MPa for aluminum alloy), lubricant thermal breakdown at 120°C (mineral oil flash point), shaft bending moment exceeding 150 N·m**.

### 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.
