# Industrial Specification: Electrostatic Powder Booth

## 1. Technical Definition
Enclosed chamber where electrostatic powder coating is applied to metal workpieces

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **60-90 kV electrostatic voltage, 0.5-2.0 bar compressed air pressure, 15-35°C ambient temperature**. Failure boundary: **Electrostatic voltage exceeding 100 kV causes dielectric breakdown of air (3×10^6 V/m breakdown strength), powder flow rate below 0.1 g/s causes insufficient coating coverage, humidity above 80% RH causes powder agglomeration**, Mechanism: **Corona discharge at high voltage gradients exceeding air's dielectric strength (ε_r=1.0006, breakdown field 3 MV/m), powder triboelectric charging failure below 10^-4 C/kg charge-to-mass ratio, laminar-turbulent flow transition at Reynolds number &gt;2300 causing uneven deposition**.

### 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.
