# Industrial Specification: Solution Tank

## 1. Technical Definition
A container within a CIP cleaning system that stores and supplies cleaning or sanitizing solutions for circulation through process equipment.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-3.0 bar (7.25-43.5 psi) working pressure, 5-85°C temperature range**. Failure boundary: **Material yield stress at 4.2 bar (60.9 psi) for 316L stainless steel, 90°C thermal limit for chemical stability**, Mechanism: **Stress corrosion cracking from chloride ion concentration exceeding 25 ppm at temperatures above 60°C, combined with cyclic pressure loading exceeding 2.5 bar amplitude**.

### 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 |

- **Caution**: 

### Q: What is the primary function of a solution tank in a CIP system?
**A**: A solution tank stores and supplies cleaning or sanitizing solutions that are circulated through process equipment to remove contaminants and maintain hygiene standards in manufacturing operations.

### Q: Why is stainless steel 316L used for solution tanks?
**A**: Stainless steel 316L offers superior corrosion resistance against cleaning chemicals and sanitizers, maintains hygiene with smooth surfaces, and provides durability for industrial environments in machinery manufacturing.

### Q: What components are typically included in a solution tank BOM?
**A**: Standard components include the tank shell/body, level sensors for solution monitoring, manway/cleaning ports for access and maintenance, and insulation jackets to maintain solution temperature during circulation.
