# Industrial Specification: Liquid Drainage System

## 1. Technical Definition
A system designed to collect and remove separated liquid droplets from a demister or mist eliminator.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-6.0 bar differential pressure across drainage ports**. Failure boundary: **Liquid accumulation exceeding 80% of demister pad void volume**, Mechanism: **Surface tension-induced liquid bridging between demister fibers exceeding 0.072 N/m at 20°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.

| Symbol | Variable Definition | Localized Reference |

## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are available for the liquid drainage system?
**A**: Our liquid drainage systems are available in stainless steel (304, 316L), carbon steel, and plastic materials including PP and PVC to suit various industrial applications and chemical compatibility requirements.

### Q: How does the liquid drainage system work with demisters?
**A**: The system collects separated liquid droplets from demisters or mist eliminators through collection channels/gutters, then efficiently removes the liquid via drain pipes or nozzles, preventing re-entrainment and maintaining system efficiency.

### Q: What are the main components of the liquid drainage system?
**A**: The system consists of two primary components: collection channels or gutters that capture liquid droplets, and drain pipes or nozzles that remove the collected liquid from the system to prevent accumulation.

## 6. Manufacturing Compliance
- ISO 14001:2015 - ENVIRONMENTAL MANAGEMENT SYSTEMS
