# Industrial Specification: Flow Control Gate

## 1. Technical Definition
A mechanical device used to regulate, start, or stop the flow of material within a distribution launder system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-2.5 MPa (1-25 bar) differential pressure across gate**. Failure boundary: **Gate seal failure at 3.0 MPa differential pressure or 150°C seal temperature**, Mechanism: **Seal material yield strength exceeded (EPDM rubber: 15 MPa tensile strength, 150°C thermal limit) causing permanent deformation and leakage**.

### 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.
