# Industrial Specification: Backwash Control Module

## 1. Technical Definition
Electronic control unit that manages the backwash cycle in filtration systems.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-6.0 bar (7.25-87.0 psi)**. Failure boundary: **8.0 bar (116.0 psi) differential pressure across solenoid valves**, Mechanism: **Hydraulic hammer exceeding solenoid valve structural yield strength (316 stainless steel, 290 MPa yield)**.

### 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.
